POM modified toughening granulator, PBT modified toughening granulator

& Modified toughening granulator
Improve impact strength and low temperature resistance
Polyacetal plastic has excellent properties of wear resistance, high surface hardness, low cost, and also has a very low friction coefficient and very Good geometric stability
However, polyacetal products are prone to cracking during production and use, are not resistant to bending, have low elongation, and have no resilience, which seriously affects the use of the product. For example, plastic buckles and plastic fasteners need to have relatively good resilience and toughness, and plastic rivets and screw seats need to have relatively high elongation and toughness. Without the use of toughening agents (anti-impact agents), they cannot meet the functional requirements. . Nowadays, many users are gradually starting to use tougheners, which have improved the service life of the products and received good results.
The toughening agent products produced by the company do not affect the wear resistance of the product. They can be added directly and stirred evenly before injection molding or extrusion. They are easy to use. In the case of adding % proportion, the impact resistance is generally increased by more than twice, while the elongation of plastic products is increased by more than %, the resilience is improved, and the low temperature resistance is also improved.
B modified toughening granulator
Improve the impact strength and low temperature resistance of B products
B has high heat resistance, fatigue resistance, self-lubricating, low friction coefficient, and weather resistance It has low water absorption, only .%, and maintains various physical properties (including electrical properties) in a humid environment. It has electrical insulation properties, can crystallize quickly at low temperatures, has good formability and other advantages.
But the disadvantages of B are low notched impact strength and large molding shrinkage. Therefore, most of them are modified with glass fiber reinforcement or inorganic filling. Their tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work for a long time at ℃, but it also brings the disadvantage of inconsistent longitudinal and transverse shrinkage of the product, which easily causes the product to warp. It brings all kinds of inconvenience to the use of product B.
For this reason, the B toughening agent specially developed by the company can effectively eliminate the defects of low notched impact strength, large improvement shrinkage, and easy warping of products. It can be added directly and stirred evenly before injection molding or extrusion. It is easy to use.
In the case of adding % proportion, the impact resistance of ordinary B plastic products is generally more than doubled, and the elongation rate is increased by more than %
The impact strength of B products modified by glass fiber reinforcement or inorganic filler modification It more significantly improves the resilience and low-temperature resistance of B plastic products.
