GTF-650 is an ultra-high molecular weight silicone powder modified with special functional groups, independently developed by Shanghai Handian New Materials Co., Ltd. It improves the flowability and mold release performance of plastics during processing; significantly reduces the surface friction coefficient of finished parts, enhances slip properties, improves surface gloss, imparts a silky tactile feel, and increases wear and scratch resistance. It exhibits excellent high-temperature stability and non-migrating properties with no blooming. It also improves the dispersion of inorganic powders.

The product can be extruded and pelletized after being mixed with other raw materials at a proper ratio.

（Recommended addition level: 0.5%–1.5% improves processability, flowability, and mold release; 1.5%–2.0% improves surface properties including slip, gloss, scratch resistance, and wear resistance.）
