Milled high‑silica glass fiber powder is produced by pulverizing high‑silica glass fiber into fine fibrous powder. After silane surface modification treatment, the product obtains good hydrophobic property and favorable interfacial affinity with polymer resin. It functions as heat‑resistant and reinforcing filler for plastics and coatings, improving heat distortion temperature, mechanical strength and scratch resistance of final products.

Product Detail

Product Detail Page: This milled high‑silica glass fiber powder retains intrinsic high‑silica glass merits including outstanding thermal stability and high‑temperature resistance. Short fibrous particle morphology provides skeleton supporting effect inside resin matrix. Silane surface modification removes hydroxyl groups on fiber surface, reduces moisture absorption, and improves wet‑out behavior when mixed with thermoplastic resins and coating binder systems.

In plastic modification applications, the short fibrous fragments are uniformly dispersed throughout the polymer matrix. The fiber skeleton restricts molecular chain movement under thermal load, effectively raising heat‑distortion temperature, flexural strength and tensile modulus of plastic compounds. It helps to suppress thermal expansion and reduces thermal shrinkage for molded plastic components.

Within coating formulations, this filler enhances scratch resistance, anti‑abrasion performance and thermal insulation property of cured coating films. It reduces film shrinkage during curing, minimizes pinholes and cracking defects for thick‑build industrial coatings.

Fiber length distribution is strictly controlled during milling process to avoid excessive long fiber agglomerates, which guarantees homogeneous dispersion during high‑speed mixing, extrusion and coating grinding procedures. It is compatible with PA, PPS, PBT, PP, epoxy resin, polyurethane and various solvent‑based and solvent‑free coating systems.

It is widely applied in high‑temperature resistant modified engineering plastic parts, electrical insulation plastic components, anti‑scratch industrial protective coatings, and heat‑resistant primer formulations.

Store the material under sealed, dry and cool warehouse conditions, keep away from moisture. Standard industrial packaging is 25‑kg multi‑layer paper bag for bulk shipment.
