शुद्ध ची घनता पहापत्रक is 1.3g/cm3. peek polyether ether ketone is a special engineering plastic with excellent properties such as high temperature resistance, self-lubricating, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, and shift start disks. Wait. If the पहा material is added with glass fiber, carbon fiber or HPV (graphite, carbon fiber, PTFE), the density is about 1.45g/cm3.
1. The injection molding shrinkage rate of पहा plastic raw materials is small, which is very good for controlling the dimensional tolerance range of पहा injection molded parts, so that the dimensional accuracy of पहा parts is much higher than that of general plastics;
2. थर्मल विस्ताराचे गुणांक लहान आहे. तापमानातील बदलांसह (वातावरणाच्या दरम्यान वातावरणीय तापमानात वाढ किंवा घर्षण उष्णतेमुळे), भागांचे आकार खूप कमी बदलतात;
3. चांगली मितीय स्थिरता. प्लॅस्टिकची मितीय स्थिरता अभियांत्रिकी प्लास्टिक उत्पादनांच्या आयामी स्थिरतेस वापर किंवा साठवण दरम्यान संदर्भित करते, कारण पॉलिमर रेणूंची सक्रियता ऊर्जा वाढते, ज्यामुळे साखळी विभाग काही प्रमाणात कर्ल होतात;
4. पहा has outstanding heat-resistant hydrolysis properties, and has low water absorption in high temperature and high humidity environments, and there will be no obvious changes in size due to water absorption of general plastics such as nylon;
