Glass Warm Edge Spacer Special Glass Fiber Reinforced PP Compound

Warm edge spacers are core energy-saving parts for insulated windows, cutting heat transfer and preventing edge condensation. Exposed to extreme temperature shifts, UV rays and moisture outdoors, plus sustained glass weight pressure, they demand substrates with exceptional rigidity, heat resistance, dimensional stability, impact and weather resistance. Today we introduce our tailor-made glass fiber reinforced PP for warm edge spacers.

Traditional aluminum spacers create thermal bridges with high heat conductivity; neat PP lacks stiffness and warps under high heat. Our glass fiber reinforced PP solves these issues and is now the mainstream material for passive house & system window warm edge strips.

High flex modulus up to 9800 MPa, heat deflection temperature max 155°C: no warping under day-night temperature cycles, tough against low-temperature cracking

Molding shrinkage 0.3%–0.5%: precise dimensions for all special-shaped spacer extrusion

Outstanding impact resistance, stable batch performance after full lab testing, boosts finished product yield by 5% and cuts production waste

Founded in May 1997, Qingdao Zhongxin Huamei Plastic Co., Ltd. is a Taiwan-invested joint venture with Chi Mei Corporation, a national high-tech enterprise integrating R&D, manufacturing and technical service of modified & color plastic pellets.

Our GF-reinforced PP drastically blocks heat exchange at glass edges to stop condensation and mold. It resists acid, alkali and UV aging without yellowing or cracking after long outdoor service. Compatible perfectly with butyl and silicone sealants, it maintains airtightness of insulated glass units and slows inert gas loss, fully meeting green & ultra-low energy building standards. Widely applied in broken-bridge aluminum windows, customized system windows and curtain wall glass spacers.
