The PE rod is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance (with a minimum usage temperature of -70~-100 ℃), good chemical stability, low water absorption, and excellent electrical insulation performance; Good stretchability; Good electrical and dielectric insulation; Low water absorption; Low water vapor permeability; Good chemical stability; Tensile resistance; Non toxic and harmless. High density polymer polyethylene (HDPE) has good impact resistance and low temperature resistance. Due to its non polarity, its electrical properties are excellent and can be used for high-frequency and high-voltage insulation. PE has good chemical stability and can withstand corrosion from acid, alkali, and salt water solvents at room temperature. Such as dilute hydrofluoric acid, dilute nitric acid, hydrochloric acid, phosphoric acid, formic acid and acetic acid at any concentration, but not resistant to strong oxidants, such as Oleum and chromic acid.

The scientific name of POM (Polyoxymethylene), also known as (Saigang bar, special steel bar), is called POM for short. POM has good comprehensive properties. It has high hardness in thermoplastics, and is one of the varieties of plastic materials whose mechanical properties are closest to metals. Its tensile strength, bending strength, fatigue strength, abrasion resistance and electrical properties are very good. Main performance: High mechanical strength, high rigidity, high hardness, excellent elasticity, sliding and wear resistance, good creep resistance, even at low temperatures, high impact strength, excellent dimensional stability, and excellent mechanical performance. It has high mechanical strength and rigidity, high fatigue strength, environmental resistance, good resistance to organic solvents, strong resistance to repeated impacts, a wide temperature range of use (40 ℃~120 ℃), good electrical properties, good resilience, self lubrication, good wear resistance, and excellent dimensional stability. Product application: POM is widely used in the manufacturing of various sliding rotating machinery, precision parts, gears, bearings, etc. The usage industry covers various fields such as automobiles, electronics, clothing, healthcare, machinery, and sports equipment. Due to the high internal stress in POM, in order to prevent stress deformation, internal stress must be eliminated before processing to prevent bending deformation.

The product has excellent tear resistance, oil resistance, high temperature resistance, corrosion resistance, insoluble in water and any solvents, non-toxic and odorless, and stable chemical properties. High adsorption performance, good thermal stability, and high mechanical strength. Working in oil media in low and high temperature environments, it can punch oil seals, washers, and seals, with good sealing performance, suitable for environments with high pressure requirements.

Industrial grade silicone tubing can be used for various carrier encapsulation and diversion, meeting environmental protection standards, with a wide range of applications, health and hygiene, resistance to impact and tear. Determination method: Baking with fire will produce white residue. Hardness: 55-60, tensile strength: ≥ 6.5.
