Aging pbt, pbt, SENXIN plastic

 PBT injection before drying must be about 3 hours at a temperature of high impact pbt 110 ~ 120 ℃, the molding temperature of 250 ~ 270 ℃ pbt, mold temperature control at 50 ~ 75 ℃ appropriate. Because the material is cooled from a molten state, is immediately solidified crystallization, so the cooling time is short; if the nozzle temperature abuse (low), runner (outlet) easy to be cooled and solidified, the phenomenon appears gag. If the cylinder temperature exceeds 275 ℃ or melt residence time of over 30 minutes in the barrel, can lead to brittle materials decompose. When required a larger nozzle into the plastic injection molding PBT, not to use hot runner systems, mold venting want good, to use "high-speed, medium pressure, temperature" conditions forming, plus fiberglass fireproof material or material not appropriate outlet PBT recycling, clean feed tube UV pbt PE or PP materials required when stopping to avoid carbonation. Modified PBT plastic means adding a small inorganic or organic molecule in the polymer (resin), by physical or chemical action pbt weatherability, giving it certain properties (machining performance) or it certain properties improved. Such as toughening, enhanced by plastic, flame retardant, etc., and by making plastics modification technology has become the fresh features, among which should belong in the automotive and home appliances, application and development potential of modified plastics most enormous of PBT. Modified PBT plastic is the most important automotive lightweight material, which not only can reduce about 40% of quality parts, but also can make the procurement costs of about 40%, so in recent years, the amount of the rapid rise in the car. Currently automotive interior parts of the plastic has been basically achieved, "plastic steel," the car is being driven by the development of modified PBT plastics in automotive applications toward a wider area of ??continuous innovation.
