The characteristics of PP Polypropylene Pan Head Slotted Screws are as follows:
1, physical properties: PP (polypropylene) is a non-toxic, odorless, tasteless milky white, highly crystalline polymer with a density of 0.90-0.91g/cm3, exceptionally stable to water, 24 hours in the water absorption of 0.01%, the molecular weight of 8-15 million between. The molecular weight is between 8-15 million. It has suitable molding properties, but the shrinkage rate is significant, and it is easy to make thick-walled products with depression. The product's surface gloss is good and easy to color.
2, mechanical properties: PP (polypropylene) of high crystallinity structural regularity has good mechanical properties, its strength, and hardness, elasticity is relatively good, but at room temperature and low temperature, the impact strength is poor, the molecular weight increases, the impact strength is also increased, but molding and processing performance deterioration. PP (polypropylene) Pan Head Slotted Screws The most prominent performance is the resistance to bending fatigue. The most outstanding property of PP (Polypropylene) Pan Head Slotted Screws is resistance to flex fatigue. The dry friction coefficient is similar to nylon's but not as good as that under lubricating oil.
3, thermal properties: PP (polypropylene) has good heat resistance, a melting point of 164-170 ℃, made of PP Plastic Pan Head Slotted Screws can be sterilized at temperatures of more than 100 ℃ for sterilization of medical equipment used; in the absence of external forces, 150 ℃ does not deform—embrittlement temperature of -35 ℃.
4, chemical stability: PP (polypropylene) Pan Head Slotted Screws of chemical stability is very good. In addition to concentrated sulfuric acid and concentrated nitric acid erosion, various other chemical reagents are relatively stable. Still, low molecular weight aliphatic hydrocarbons, chlorinated hydrocarbons, etc., can make the PP (polypropylene) soften and dissolve.
5, electrical properties: PP (polypropylene) high-frequency insulation is excellent because it almost does not absorb water, so humidity does not affect insulation properties. PP (polypropylene) Pan Head Slotted Screws have a high dielectric coefficient, with the temperature rise, can be used to make heated electrical insulation products connected to the fastening, and its breakdown voltage is also very high. PP (polypropylene) voltage and arc resistance are good. PP (polypropylene) voltage and arc resistance are good, but the degree of static electricity and copper contact are easy to age.
6, weathering: PP (polypropylene) is very sensitive to ultraviolet light, adding zinc oxide, bis(2-month) laurel thiopropionate, carbon black or similar opalescent fillers can improve the PP Plastic Pan Head Slotted Screws aging resistance.
Product Specification
Polyethylene is sensitive to environmental stresses (chemical and mechanical) and has poor resistance to heat aging. Its properties vary from species to species, depending mainly on its molecular structure and density. Different production methods can be used to obtain products with different densities (0.91 to 0.96 g/cm3). General thermoplastic molding methods can process polyethylene (see Plastics Processing).
Polypropylene (PP) is a common thermoplastic polymer with excellent properties. It is lightweight, chemical resistant, has good insulation, and has high impact resistance. Due to these properties, Polypropylene PP Plastic Pan Head Slotted Screws are widely used in several industry sectors. The following are some of the main applications of Polypropylene Pan Head Slotted Screws:
1. Packaging industry: PP polypropylene is widely used in food packaging, pharmaceutical packaging, daily necessities packaging, etc. PP Plastic Pan Head Slotted Screws are made of polypropylene due to their lightweight, chemical resistance, and abrasion resistance; packaging materials are made of polypropylene in the transportation and storage of the performance of an outstanding fastening effect.
2. Textile industry: PP polypropylene fibers are used in the manufacture of a variety of textiles, such as carpets, ropes, and industrial filtration materials. Polypropylene fiber Pan Head Slotted Screws are lightweight, abrasion-resistant, and do not easy to absorb water and other characteristics.
3. Medical Devices: Because polypropylene is biocompatible, PP Pan Head Slotted Screws are widely used in the field of medical devices, including medical syringes, test tubes, medical packaging, and other unique parts of the fastening connection.
4. Automotive industry: PP Polypropylene Pan Head Slotted Screws are widely used in automotive interiors, body parts, and engine parts fastening connections. Its lightweight and impact resistance makes it an ideal plastic screw fastener for automotive parts manufacturing.
5. Construction and building materials: Polypropylene Pan Head Slotted Screws are used in the construction field to manufacture pipes, insulation materials, flooring materials, and other parts of the fastening connections. Its chemical resistance and UV resistance make it excellent for outdoor applications.
6. Electronics and electrical appliances: PP polypropylene plastic Pan Head Slotted Screws are used in the field of electronics and electrical appliances for the manufacture of fastening connections to cable sheaths, sockets, switches, transformers, and other components; PP plastic Screws insulation properties are essential.
7. Household goods: Polypropylene Pan Head Slotted Screws have many applications in the manufacture of household goods, such as chairs, garbage cans, storage boxes and other fastening connections.
8. Agriculture: Polypropylene fasteners can also be used to manufacture agricultural products, such as agricultural film, water pipes, agricultural packaging, and other fastening connections.
9. Toys: Due to the low cost of polypropylene, and sound processing, there is also a wide range of PP material in the toy manufacturing plastic Pan Head Slotted Screws to carry out fastening connections.
Polypropylene Pan Head Slotted Screws are versatile plastic fasteners that are suitable for many different applications and are widely used in industry, daily life, and specific industries.
