Characteristics of radiation-proof boron-containing polyethylene board:
Wear resistance: Due to its unique molecular structure, the wear resistance is higher than that of general metal plastic products, 6.6 times that of carbon steel, 5.5 times that of stainless steel, 27.3 times that of brass, 6 times that of nylon, and 5 times that of PTFE. times.
Non-stick: The surface tension is large and the friction coefficient is small, so it is not compatible with common substances, so it is not easy to stick to scale.
Small coefficient of friction: Because of its waxy substance, it has good self-lubrication, small flow resistance and energy saving.
Chemically resistant to acid, alkali and salt media.
Good impact resistance: even at low temperature, it is subjected to strong fracture.
Content of boron carbide: ten percent (by weight)
Density: ≥1.028g/cm3
Density difference: ≤0.01g/cm3
Thermal deformation temperature (load ρ=0.46Mρa): 72℃
Linear expansion coefficient: 8.933×10-51/℃
Heat resistance temperature: 126℃ (DTA measurement value)
Thermal strength: ≈ 24MPa
Impact strength (notch): ≈ 19KJ/m2 Electrical insulation: It has good electrical insulation and high insulation resistance.
The boron-containing polyethylene board feels like wax, has excellent low temperature resistance (low operating temperature can reach -70 ~ -100 ℃), good chemical stability, and can resist the erosion of most acids and alkalis (not resistant to acids with oxidizing properties) , insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation performance; low density; good toughness (also suitable for low temperature conditions); good stretchability; good electrical and dielectric insulation; low water absorption; Low rate; good chemical stability; tensile strength.
