Many people don't know about PVC injection particles. They know this kind of products when they read the instructions of some products. But do not understand the PVC injection particles, the following small series for you to introduce the product characteristics of PVC injection particles.

  General performance

  The appearance of PVC injection particles is opaque and ivory colored. The products can be colored and have high gloss. The relative density of ABS is about 1.05, and the water absorption is low. ABS has good adhesion with other materials and is easy to be printed, coated and plated. The oxygen index of PVC particles is 18-20, which is a flammable polymer. The flame is yellow, with black smoke and a special odor.

  mechanical property

  PVC particles have excellent mechanical properties, excellent impact strength and can be used at very low temperature; PVC particles have excellent wear resistance, good dimensional stability, and oil resistance, which can be used for bearings under medium load and speed. The creep resistance of PVC particles is larger than that of PSF and PC, but smaller than that of PA and POM. The bending strength and compressive strength of ABS are poor among plastics. The mechanical properties of PVC particles are greatly affected by temperature. PVC plastic particles

  Thermal Properties

  The thermal deformation temperature of PVC injection molding particles is 93-118 ℃, and the product can be increased by about 10 ℃ after annealing treatment. PVC particles can still show certain toughness at - 40 ℃, and can be used in the temperature range of - 40-100 ℃.

  Electrical performance

  PVC injection molding particles have good electrical insulation and are hardly affected by temperature, humidity and frequency, so they can be used in most environments.

  Environmental performance

  PVC injection molding particles are not affected by water, inorganic salts, alkali and various acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons, which will cause stress cracking when corroded by glacial acetic acid and vegetable oil. ABS has poor weather resistance and is easy to degrade under the action of ultraviolet light; the impact strength of ABS decreases by half after half a year outdoors.
