Laptop keyboard film is mainly composed of silicone and TPU materials, which is blister molding and used for waterproof to protect keyboard.
TPU keyboard film hardness is 90A, harder than silicone, with better handfeeling when typing. TPU keyboard film is thinner, better for the cooling for keyboard, and wear-resistance, high transparency ,keeps excellent physical properties of TPU resin elastors.
Silicone is also named as silica gel, is a highly active adsorption material, which is an amorphous substance. Silicone is easy to vacuum as open porous structure, strong adsorption for variety of substances
Silicone keyboard film is with good ductility, high tensile, well fit and no easy to deform.
POLYSAN is a professional TPU film for keyboard, environmentally friendly, Inhibit bacteria, dustproof, odorproof, waterproof and wear-resistant, high quality.
