Material properties

It is E‑glass continuous roving T838T treated with special silane‑based sizing optimized for polypropylene matrix. It features good strand integrity, low fuzz generation and excellent wet‑out performance with PP resin. Available in multiple tex and filament diameter options, it delivers stable interfacial bonding, helping modified PP composites achieve consistent mechanical performance.

Applications

Continuous glass fiber roving T838T is specially developed for PP thermoplastic reinforcement. It is widely applied for LFT long fiber extrusion process to produce long‑glass‑fiber reinforced PP pellets, which are further made into automotive parts, household appliance components and various high‑strength industrial thermoplastic products.

Manufacturing process

It is manufactured by melting E‑glass mineral raw materials to form glass filaments, coated with customized silane sizing agent compatible with PP resin, then gathered into continuous roving. Finished roving is wound onto bobbins, ready for direct feeding into LFT production lines for compounding with polypropylene.

Technical specifications

The technical specifications may vary depending on production batches, but typically include tex, filament diameter and compatible resin type. For example, typical tex of T838T are 2400 and 3600; available filament diameters cover 15 μm and 17 μm; it is compatible with PP resin matrix. Note: actual composite performance will deviate subject to PP resin grade and processing conditions.

Safety and environmental considerations

Standard industrial PPE is recommended during material handling to avoid inhalation of fine glass dust. Store the product in cool, dry conditions away from rain and direct sunlight. Recommended storage temperature: 5℃‑35℃, relative humidity 35%‑65%. Keep packaging sealed if not in use to prevent moisture absorption. For best performance, use within 12 months upon receipt. Follow local regulations for waste disposal of glass‑fiber waste.

Overall

T838T is a standard‑grade E‑glass continuous roving tailor‑made for PP thermoplastic reinforcement. With multiple tex and fiber diameter selections and excellent PP‑compatible sizing, it is widely adopted by composite manufacturers for LFT‑PP high‑performance thermoplastic materials.
