Blister material characteristics
HIPS density 1.0, shrinkage rate 1.005, environmental protection and non-toxic can be directly in contact with food, good plasticity and easy to form, poor toughness and brittle, low static electricity, flammable
PP Density 0.92, shrinkage 1.015, light and soft, the lightest general-purpose plastic, excellent chemical stability and insulation, non-toxic and good moisture resistance, poor cold and oxidation resistance, easy to shrink and deform
PETG Density 1.36, shrinkage 1.005, good transparency, good chemical resistance, non-toxic, reliable hygiene, excellent impact resistance and rigidity, good thermoforming properties, low flammability and fire resistance, non-combustible
ABS density 1.05, shrinkage 1.005, good molding processability, excellent comprehensive mechanical strength, good cold resistance, CHIMEI 757 for general purpose, 777D for high temperature, 765A for fire resistance.
PC density 1.4, shrinkage 1.005, high impact strength, also called bulletproof rubber, good flame resistance, little change in physical properties from -100 degrees to 126 degrees, transparency 86~89%, disadvantage not resistant to gasoline and solvents, not easy to shape
HDPE density 0.96, shrinkage 1.018, acid and alkali corrosion resistance, good insulation, small water absorption, not easy to moisture, temperature resistance -70 degrees to 100 degrees, poor weather resistance, sunlight exposure makes the products brittle, easy to deformation and aging, glossy than PMMA density 1.2, shrinkage 1.004, high permeability light transmission rate of 92%, excellent weather resistance, 4 years of natural aging except for a slight yellowing of its Physical properties almost unchanged
PVC Density 1.4, shrinkage 1.02, excellent electrical insulation, slightly less resistant to acids and alkalis and solvents than PP and PE, good flame retardancy, poor heat resistance, poor cold resistance, low impact strength, poor thermal stability and easy decomposition
