The main difference between TPE and PVC is performance;TPE is a thermoplastic elastomer material, does not contain plasticizer, is environmentally friendly non-toxic material.PVC is polyvinyl chloride, which has been identified by the World Health Organization as a class 3 carcinogen, and plasticizers have been added during processing.Secondly, there is a difference in hardness between the two;The hardness of TPE and PVC was 10~95A and 10~20P respectively.In addition, TPE and PVC are quite different in feel, combustion state, flame retardant level and temperature resistance.
TPE is a thermoplastic elastomer material with the high elasticity, strength and resilience of rubber.TPE material does not contain plasticizer, is an environmentally friendly non-toxic material.
PVC is polyvinyl chloride, which has been identified by the World Health Organization as a class 3 carcinogen, and plasticizers have been added during processing.PVC products in higher temperature, will slowly decompose hydrogen chloride gas, this gas is harmful to the human body, easy to pollute the environment.
TPE: 10 ~ 95 a.TPE hardness is usually expressed in Terms of Shaw hardness A, and special hardness is measured in terms of OO and D.
PVC: 10 ~ 20 p.PVC domestic often according to the added plasticizer and PVC raw material percentage P% to table, the hardness unit is P.
It should be noted that the higher the HARDNESS value of TPE, the harder the material is.The higher the hardness of PVC, the softer the material.
TPE has a soft touch, high elasticity and mild texture, but it has a weak elasticity and a soft touch.
PVC handle is relatively hard, adding plasticizer can make plastic products become soft, easy to bend.
TPE: Fragrant smell, yellow on the flame and blue on the flame.
PVC: the smell of chlorine, the flame on the yellow under the green, the fire from the self-extinguishing.
In terms of flame color, WHEN TPE burns, the flame root is blue and PVC is green.
In the absence of materials with added flame retardant, PVC flame retardant is better than TPE.
TPE flame retardant level: UL94-HB, in case of fire combustion, from the fire will not go out.
PVC flame retardant level: UL94-V2, with self-extinguishing, ignition combustion, after the evacuation of the ignition source, the flame will generally go out.
TPE temperature resistance: -50~90℃;
PVC temperature resistance: -10~80℃;
TPE has better cold resistance and high temperature resistance than PVC, but PVC material has high chemical resistance, corrosion resistance and ozone resistance.
