填充聚四氟乙烯制品

Filled PTFE Article

【特征Features 】

填充聚四氟乙烯制品选用填充聚四氟乙烯树脂经模塑加工制成。悬浮聚合聚四氟乙烯树脂与各种填充剂混合成填充聚四氟乙烯树脂。适合与聚四氟乙烯混合的多种填充剂中有玻璃纤维、碳纤维、锡青铜及润滑剂（如石墨、二硫化钼）并已广泛用于规模生产中。填充聚四氟乙烯与纯聚四氟乙烯相比具有较高的压缩强度，耐磨、导热好、热膨胀减少的优点。

Filled PTFE article is manufactured by moding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with fillers of many differents kinds. Amongst the many fillers suitable for compouding with PTFE, glass fiber, carbon fiber, Bronze and also lubricating materials like graphite, molybdenum disulphide, have been widely used in large scale production, Broadly speaking PTFE compounds have the following advantage over unfilled.

PTFE. Improved compression strength

Improved thermal conductivity

Dereased thermal espansioin

Improved abrasion resistance
