Modified POM Enhances Plastic Hardware for Doors and Windows
Jul 02,2026
Mass production of glass-fiber-reinforced POM has begun, enhancing the durability of friction-type plastic components for doors and windows.
Load-bearing friction plastic accessories for doors and windows complete material iteration. Glass fiber reinforced modified POM realizes mass production, widely used in core parts such as sliding window lifters, center column injection sheets and sliding anti-collision rubber. Raw POM turns brittle under low temperature and wears heavily under long-term friction. Modified formula blended with nano glass fiber improves tensile strength by 33% and cuts wear loss rate by 56%, without cracking or deformation under -35℃.
Two-stage underwater pelletizing technology avoids glass fiber agglomeration. The material has good fluidity for thin-wall and buckle-shaped parts injection, with no fiber floating on finished surface to skip secondary spraying and reduce VOC emissions. UV-resistant crosslink additives prevent yellowing and aging for ten years outdoor, suitable for balconies and French windows. Popularization of high-end system doors and windows raises service life standards for plastic accessories. Modified POM parts match the whole service cycle of windows. The industry is optimizing formulas to cut raw material cost and develop recyclable modified materials. This material fits casement, sliding and broken bridge aluminum profiles, becoming mainstream substrate and upgrading sealing & sliding accessory quality overall.
