Judging from the current situation, PBT plastic itself is a milky opaque crystalline thermoplastic resin, relatively speaking, it has very good comprehensive properties, excellent coloring performance, and its elasticity is also very good, so its rigidity and hardness are very good. On top of that, the stiffness of this product is relatively closer to that of metal than its rigidity.
UV-resistant PBT plastic has very good tensile strength, its flexural strength and creep resistance, and some fatigue resistance, which is also very good, with very good internal repeated impact, and his back and forth recovery is also very good.
In addition, the chemical resistance of UV-resistant PBT plastic products is relatively excellent, in addition to strong acids or some other organic chemicals, it is also very stable for some other cosmetics, and particularly durable, and the mechanical properties are relatively little affected by temperature, so it has a very high thermoplasticity, it can be said that it has a strong temperature of heat deformation.
However, one of the biggest features of anti-ultraviolet PBT products is that its flame retardancy is relatively poor, and once it is hot, it is very easy to burn, and even if some flame retardants are added, it can not get a series of satisfactory requirements, its weather resistance is not particularly ideal, and the outdoor temperature should also be added with some stabilizers, only in this way can it play some of its original characteristics.
The formaldehyde crystallinity inside the whole product is relatively high, with very good mechanical strength, rigidity and thermal denaturation temperature, it is also much better than some other formaldehyde, the melting point of this formaldehyde is relatively low, the stability is relatively poor, but its chemical corrosion resistance is very good, and it has very good fluidity, and its performance is much better than that of homopolymeric formaldehyde, at the same time, this newly developed product itself has ultra-high fluidity, so it has strong impact resistance, and, also with infinite filling.
The water absorption rate of UV-resistant PBT plastic is significantly larger than 0.2%, and the temperature of this product is very similar to the temperature of the decomposition of the product itself, and the molding is also very poor, and it can be injection molding, blow molding, printing, or some other methods to be processed in a short time, and the shrinkage rate is relatively large.
