What is the difference between TPE and PVC? Each material has its own advantages and disadvantages, and each has its own value. The key is to choose the right material according to your product requirements. In the long run, TPE is recommended by Dechuang Chemical Co., Ltd. in response to the country's environmental protection policy. Because TPE is environment-friendly and tasteless, and also has the advantages of rubber and plastic, waste nozzle materials can be recycled, saving resources, reducing costs, and no harm to the environment and human body. All TPE is praised as a new generation of "rubber and plastic gold" by the industry.
What is the difference between TPE and PVC?
1. According to the material characteristics, TPE is environment-friendly and nontoxic, PVC is added with plasticizer, etc. It is toxic and not environment-friendly, and waste materials will destroy the environment when burned.
2. In terms of hardness, TPE hardness is 0-100A and PVC hardness is 40A-100A.
3. In terms of hand feeling, TPE feels good, smooth, soft and elastic, while PVC feels relatively hard.
4. Judging from the color of the burning flame, when TPE burns, the root of the flame is blue, while PVC is green.
5. From the perspective of smell, TPE smells tasteless or very small, burning with aromatic flavor, while PVC burns with chlorine odor and unpleasant taste.
6. From the cost point of view, TPE can be recycled, but PVC cannot. In terms of price, PVC materials are cheaper.
7. In terms of physical properties, TPE material has superior physical properties. Soft touch, high elasticity, mild texture, adjustable surface gloss and fog brightness, low smoke and halogen-free, scale-free, excellent oil resistance, weather resistance, aging resistance, buckling resistance, ozone resistance, chemical resistance and other properties. PVC materials have high chemical resistance, corrosion resistance, but not ozone resistance. However, it can be corroded by concentrated ammonium oxide such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.
8. Judging from the proportion. The specific gravity of TPE material ranges from 0.88 to 1.2, while that of PVC ranges from 1.3 to 1.4.
