CPE 135A Material
Introduction
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance.
Effect of CPE additive amount on PVC
When the added amount is less than 10 minutes, the impact strength of PVC increases rapidly with the addition of CPE. However, if the added amount of CPE is further increased, the impact strength of PVC is rarely improved.Therefore, 8-10 portions of CPE should be added when used as an anti-impact agent. At the same time, with the increase of CPE, the tensile strength of PVC blend continues to decline and the elongation at break increases. If the product of tensile strength and elongation at break indicates its toughness, it is obvious that PVC toughness will obviously increase with the increase of CPE.Have literature thought in 8 above, CPE than precipitation in the saturated solubility of PVC and PVC, PVC as the sea, the island of CPE for micro phase separation structure, thus greatly improve the impact strength of PVC, also have literature that CPE in more than six servings, can form a network in the formula, thus impact modified effect, but the CPE at low content (e.g., 1), can not form a network in the formula system, also can’t more than its saturated solubility and precipitation in PVC, its impact in the formula of modified to little effect.
