PP placemats are non-polar and thermoplastic?

In modern life, the new material of PP can be seen everywhere, such as piping equipment, valve parts, transportation containers,rectangle PVC placemat,
medical appliances, PP placemats, etc., all of which are produced with PE boards.
In modern life, the new material of PP can be seen everywhere, such as piping equipment, valve parts, transportation containers, medical appliances, PP placemats, etc., all of which are produced with PE boards. So what kind of new material is PE board? PE board has high crystallinity, non-polarity and thermoplasticity. Simply put, it is a new type of resin gum material. The appearance of PP sheet is milky white, in a relatively small section, it is translucent, and it is chemically called polyethylene board.
In daily life, PP sheet has high corrosion resistance to chemical products, and it is not easy to absorb moisture to prevent the evaporation of moisture, so it can be used as a packaging material. Among PE sheets, HDPE has very good electrical properties and excellent insulation dielectric strength. Therefore, wire and cable equipment generally uses this material. In general, the PE sheet is chemically stable, can resist the erosion of most chemical substances, and has very good electrical properties. Its physical properties have high toughness, wear resistance and tensile strength, and are widely used in clothing, food and other industries.
PP sheet has good flame retardancy and can be filled. LDPE is also called high-voltage low-density polyethylene. It is relatively soft, has a low melting point and low mechanical strength. Therefore, it can be used to make film and wire and cable insulation. The HDPE mentioned above is also called low-voltage high-density polyethylene. Its various properties and LDPE is just the opposite, rigid material, mechanical strength, and melting point are all high, so it is suitable for PP placemats.
