PP Korea Lotte Chemical JM-350 Injection Molding Impact Resistance UV Resistance Outdoor Chair Polypropylene Plastic Raw Material
1The main component of plastic raw materials is a polymer compound matrix called resin.
2. Plastic raw materials: It is a material that is mainly composed of high molecular synthetic resin (polymer) infiltrated with various auxiliary materials or certain additives with specific uses. It has plasticity and fluidity under specific temperature and pressure, can be molded into a certain shape, and can maintain its shape under certain conditions.
3. Polymer: refers to the pure material or polymer material produced by the polymerization process. Both natural resin and synthetic resin are high molecular polymers, referred to as polymers.
4. Plastic has good insulation properties against electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption and sound elimination performance.
Most plastic raw materials are extracted from some oils. The familiar PC material is extracted from petroleum. When PC material is burned, it has a rotten fruit smell and charcoal molecules. ABS is extracted from coal. When ABS is burned out, it will be ash-like and will not bubble. POM is extracted from natural gas. When POM is burned, it will have a very smelly gas smell and white smoke.
Performance characteristics
a. Plastic materials expand when heated, and their thermal expansion coefficient is much larger than that of metals.b. The rigidity of general plastic materials is one order of magnitude lower than that of metals;
c. The mechanical properties of plastic materials will significantly decrease after prolonged heating;
d. Generally, plastic materials will experience permanent deformation when subjected to long-term stress at room temperature and under stress below their yield strength;
e. Plastic materials are very sensitive to damage from notches;
f. The mechanical properties of plastic materials are usually much lower than those of metals, but some composite materials have higher specific strength and modulus than metals. If the product design is reasonable, it will be able to play a better role;
g. Generally, the mechanical properties of reinforced plastic raw materials are anisotropic;
h. Some plastic materials absorb moisture and cause changes in size and performance;
i. Some plastics are flammable;
j. Fatigue data for plastic materials is still very limited and needs to be considered based on usage requirements.
