Material properties: High impact strength, good dimensional stability, colorless and transparent, good colorability, good electrical insulation, corrosion resistance, and wear resistance, but poor self-lubricating, prone to stress cracking, and prone to hydrolysis at high temperatures. Poor compatibility with other resins. Suitable for making small instrument parts, insulating transparent parts and impact-resistant parts. Mold performance. Amorphous material, good thermal stability, wide molding temperature range, poor fluidity. It absorbs little moisture but is sensitive to water and must be dried. The molding shrinkage is small and melt cracking and stress concentration are prone to occur, so the molding conditions should be strictly controlled and the plastic parts must be annealed.
For plastic parts with high melting temperature and high viscosity, it is better to use a heated extension nozzle.
The cooling speed is fast, the mold pouring system should be thick and short as the principle, a cold well should be set up, the gate should be large, and the mold should be heated.
If the material temperature is too low, it will cause material shortage and the plastic parts will be dull. If the material temperature is too high, it will easily overflow and the plastic parts will blister. When the mold temperature is low, the shrinkage, elongation, and impact strength are high, but the bending resistance, compression resistance, and tensile strength are low. When the mold temperature exceeds the temperature, the plastic parts cool slowly and are prone to deformation and sticking to the mold
