Use and performance

PTFE (Poly tetrafluoroethylene, abbreviated as PTFE), commonly known as "Plastic King", is a high molecular polymer made by polymerization of tetrafluoroethylene as a monomer. White waxy, translucent, excellent heat and cold resistance, can be used for a long time at -180～260ºC. This material has the characteristics of anti-acid, anti-alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is extremely low, so it can be used not only for lubrication, but also as an ideal coating for the inner layer of water pipes that are easy to clean.

The high-performance PTFE materials we provide can be used in the production and processing of various seals.

Q: Why is rubber resistant to compression and wear better than metal?: The rubber bushing is made of metal and has a flexible connection. The sheath is made of rubber

Q: How does rubber mobile phone cover change yellow?: In physical properties, rubber has swelling, rheological properties and other changes. Tensile strength, elongation at break, impact strength, flexural strength, compression ratio and elasticity decrease.

Q: What gum does rubber and metal stick together?: JL-480 black rubber instant glue: medium viscosity, high strength, etc. used for inert surface, bonding, porous, acid, vibration and heat resistance, rubber, metal, plastic bonding. The utility model can be used for large gaps and more dispensing. High viscosity, impact resistance. The curing is slow, the curing has toughness, and the adhesive force is strong. After bonding, the adhesive surface can reach two and the adhesive surface dissolves as a whole. It is a shock resistant instant adhesive, which has better seismic and stripping strength than other series. Widely used, bonding rubber, plastic, and metal as adhesive for impact resistance. It is more flexible than conventional adhesive.

Q: Is mixed silicone rubber dangerous?: With excellent thermal stability, high and low temperature resistance, can -60 to +250 DEG C under the condition of long-term work, ozone resistance, weatherability and good electrical properties, corona resistance, electric arc, electric spark is extremely strong, with chemical stability, weathering resistance, radiation resistance, physical inertia and good air permeability.

Q: Rubber Mooney value is what meaning, what is the role of: Mooney viscosity (Mooney viscosity) also called rotation (Mooney) is determined by numerical viscosity, Mooney viscometer, synthetic rubber can basically reflect the degree of polymerization and molecular weight. The rotor is a standard Mooney viscometer, at a constant speed (2 RPM), rotating in a closed chamber in the sample the viscosity change of shear resistance. The size of the sample and the rotation of the rotor during the curing process, through the force measuring device is displayed on the dial to Mooney units, at the same time interval can be read Mooney, vulcanization curve, door number rose after the first drop, 5 unit increase in the time from the lowest point called the Mooney scorch time, the Mooney scorch and then increased to 30 units and the time that scorch time.

Q: Is silicone good or rubber good?: Rubber is divided into natural rubber and synthetic rubber, natural rubber structure is isoprene polymer, synthetic rubber such as polybutadiene rubber, chloroprene rubber, styrene butadiene rubber. When rubber is deformed by the external force, the crosslinked rubber has the ability to recover quickly, and has good physical and mechanical properties and chemical stability.Silicone rubber is mainly composed of high molecular weight linear polysiloxane. The Si-O-Si key is the basic bond formed, mainly methyl silicon atoms connected, introduced a very small amount of unsaturated groups in side chain, intermolecular interactions, molecular spiral structure, methyl arrangement and can freely rotate outward, thus vulcanized silicone rubber has excellent resistance to high and low temperature (-100~315 DEG C). Weather, water repellent, electrical insulation, physiological inertia and other characteristics, are widely used in military, medical, industrial and agricultural production and people's daily life. Most importantly, there is no toxicity, as usual in pacifiers and breast implants.

Q: Why does rubber burn black smoke?: Natural rubber is the structure of isoprene polymers, itself contains a large number of carbon elements

Q: What are the rubber parts for the car?: Filter rubber parts, cloth (diaphragm), injection pump sealing ring, car frame sealing strip, door seal..... There are many, the car inside the big, small, a lot of rubber products. Watch more and you'll see.

Q: What kinds of vulcanized rubber do you have?: According to the sources and methods of raw materials: rubber can be divided into two categories: natural rubber and synthetic rubber. Among them, the consumption of natural rubber accounted for 1/3, and the consumption of synthetic rubber accounted for 2/3.
