Glass fiber roving and reinforcement products

The FY2025 business description reports sales of 320.26 ten-thousand tonnes of roving and products. This is the disclosed rounded sales figure, not production, year-end inventory or installed capacity. The broader product scope includes roving and products; it is not an electronic-yarn line output.

Roving is the coarser product family. The report gives a typical individual filament diameter of 10-20 micrometres and describes uses in composite reinforcement, electrical insulation and thermal insulation. Downstream applications include construction materials, transport, electrical and electronic equipment, energy and environmental uses, and consumer goods. For Jushi, this product path connects manufacturing output to customers making reinforced components and materials across multiple industries; the application list does not identify individual customer contracts.

The report says FY2025 glass fiber roving sales exceeded 3,200,000 tonnes. The figure is a disclosed lower bound, not an exact quantity. The filing does not establish the exact company-wide production or closing inventory quantity in this passage.

The report names glass-fiber chopped strands for heat- and oxidation-resistant reinforced nylon and chopped strands for PP reinforcement in new-energy vehicles. These descriptions identify two distinct resin/application targets within the reinforcement-product range; they do not establish a single interchangeable grade. The accompanying recognition table is useful for identifying the developments, but it is not a technical datasheet or evidence of an automotive customer's qualification. It does not give strand length, fiber diameter, glass formulation, resin loading, test conditions, customer names or sales by grade. The product targets can be recorded while those specifications and commercial quantities remain unresolved.

The FY2024 business description reports sales of 302.50 ten-thousand tonnes of roving and products. This is the disclosed rounded sales figure, not production, year-end inventory or installed capacity. The broader product scope includes roving and products; it is not an electronic-yarn line output.

The company developed more than ten major new products. It describes high-performance solutions for offshore wind, photovoltaic frames, vehicle battery boxes and hydrogen storage tanks, with customer quality certification and gradual stable batch supply. These are application-specific commercialization disclosures. The passage does not identify the customers, assign a shipment quantity to each application or state that every product was already delivering at the same stage.

China Jushi reported FY2023 sales of 2.4814 million tonnes of roving and related products. Roving consists of bundles of continuous glass filaments used as reinforcement. The disclosed quantity measures products sold across the group; it is not furnace capacity, production output or a volume attributed to an individual project. The source reports 248.14 ten-thousand tonnes, so the converted figure retains the precision of that disclosure.

The company reports obtaining additional certifications from the American Bureau of Shipping, Saudi Arabia's SABER system and the United Kingdom's WRAS water-contact scheme. The same discussion describes raw-material and chemical testing under a new supplier-management system. These disclosures explain qualification and quality-control work. They do not identify each certified product grade, certification number or a sales contract arising from certification.

The report describes glass fiber as an inorganic material used for composite reinforcement, electrical insulation, thermal insulation and circuit-board substrates. Pyrophyllite, kaolin, limestone and quartz sand are proportioned, melted at high temperature, drawn into filaments, dried and wound. Hundreds or thousands of filaments form a strand. Alkali-free, medium-alkali and high-alkali fibers are distinguished by glass chemistry. This explains the production chain and why a furnace, powder plant and weaving operation are different assets.

The company sought higher-value applications in new energy, energy-efficient buildings, vehicle lightweighting and electronic information. Product research included high-pressure pipe yarn and the development and performance improvement of shaped glass fibers. It participated in four national standards and led two covering chopped-strand flowability and roving antistatic performance. These disclosures explain both the target markets and technical work; research progress and standards participation are not shipment figures for the new products.

The report describes composite fiber as offering simpler forming, greater production efficiency, mechanical performance, repairability and recyclability than traditional glass fiber. It lists compression molding, laminated-sheet forming and winding as suitable processes, with potential uses in aerospace, automotive, construction, sports equipment and new energy. Management says the composite-fiber project had completed product appraisal and acceptance, entered stable batch production and gained recognition from major overseas customers. It separately says polypropylene (PP) composite yarn had met the requirements for industrial production through online compositing. The passage supplies no customer names, annual tonnage, separate sales, resin fraction or measured performance results. Potential applications are not disclosed deliveries to every industry, and the PP process milestone does not establish that every named technology or grade had the same composition or sales stage. Existing product-specific accounts retain the different stages for E7, LFT yarn, nylon-reinforcement chopped strands, optical-cable reinforcement, bathroom SMC yarn and rail-sleeper yarn.

The report says high-dispersion LFT yarn entered stable batch production and nylon-reinforcement chopped strands gained customer recognition and batch purchases. Optical-cable reinforcement yarn received recognition in India and Korea. SMC yarn for integrated bathrooms began batch purchases in Japan, while high-speed rail-sleeper yarn received recognition from Japan's Sekisui and reached batch production. These are product-specific statements with different stages. No annual sales amount or customer-wide exclusive relationship is inferred from them.

The report describes yarns tailored to wind-power reinforcement, high-pressure petroleum pipes, epoxy-pipe chopped-fiber applications and a composite-forming process labeled CFRT. High-performance wind-power yarn passed Siemens fatigue-test qualification and was placed on the market in large batches, according to the company. The petroleum high-pressure pipe yarn introduced in 2013 was described as qualified by Ameron after process-performance assessment and a 1,200-hour long-duration test. For epoxy pipes, the company developed chopped yarn by changing the sizing system, meaning the fiber-treatment formulation referred to in the report. It claims a greater-than 15% improvement in mechanical performance over its earlier general-purpose system, but does not identify a specific measured property or full test conditions. The pipe customer accepted its performance; a separate wind-fabric surface-yarn application was recognized by Siemens and reached batch supply. For CFRT-process yarn, the company reports good dispersion and wear resistance, domestic customer acceptance and the start of batch purchasing. The filing does not expand that process acronym or give a full process specification. These are product-specific reported stages, not independently verified certificates, customer-wide approved-supplier status or quantified annual sales. The general statements of no major orders and no major product/service change do not erase these individual developments.

The company introduced yarn for high-pressure petroleum pipes in FY2012. The annual report says the product passed comprehensive qualification by pipe manufacturer Ameron, citing process performance and a 1,200-hour long-duration test. This provides a named customer qualification milestone, which is distinct from the unnamed overseas recognition reported for composite fiber and from a product still described through R&D progress. The passage does not identify the test standard, operating pressure, temperature, or measured outcome. The duration is a reported test period, not a demonstrated pipe service life. Nor does the qualification establish approval by every regulator, the size of an order, a long-term supply contract or recognized sales. The business significance is the reported qualification for a high-end pipe application; research does not extend to investigating Ameron beyond this disclosure.

The flame-retardant glass-fiber product is designed for reinforced PA, or polyamide, materials. The company reports an FY2012 R&D breakthrough after refining its understanding of flame-retardant mechanisms, sizing raw materials and production processes. The stated purpose is to maintain flame-retardant performance while reducing the amount of flame-retardant additives used in the composite, which management links to lower composite-material cost and environmental requirements. These are company-reported technical and economic claims. The passage does not quantify the additive reduction, identify a test standard or customer, or disclose product sales. Unlike the separate composite-fiber disclosure, this paragraph does not expressly establish stable batch production. Readers should therefore distinguish the reported research advance and intended value to customers from demonstrated commercial volumes.

The newly developed pultrusion yarn is described as a direct-roving product aimed at the high end of the pultrusion market. Its disclosed customer purpose is to meet demand for higher-performance pultruded products; the report does not specify final components or named customers. Management claims shear strength more than 30% above the company's conventional pultrusion yarn. This is a relative comparison against its own product, not a claim of superiority over every competing material. The cited passage gives no test method, conditions or absolute strength value. Management also describes quality and production-cost advantages and expects the product to become a leading company product. Those descriptions and expectations do not establish market leadership, completed customer qualification, a sales contract or quantified revenue.
