Omnia Plastica PP Polypropylene

The mechanical features of PP are better than those of PE H.D. It withstands attack by alkali and acids and consequently it is widely used for components in the chemical industry when a moderate stress material is required.Features:Chemical: high chemical resistance. Tensile stress: very high among the polyolefins. Low specific gravity. Easy machinability on mechanical tools. It can be welded. Good stability to temperature. Colour: grey RAL 7032 and naturalWeak Point:Compared to the engineering plastics it has low thermal and mechanical properties: tensile stress, flexural and compressive strength, etc. Compared to PE it is more rigid but less shock resistant.Application:Chemical: the widest application field for PP is the chemical industry. Thanks to its high resistance to acids and alkali and its higher temperature resistance than PVC, it is used for components in the chemical, galvanic and petrochemical industries to produce valves, flanges, gears, etc.Food contact: it is physiologically inert, so in natural form, it is approved for use in contact with food. Electrical: good dielectric properties. Weather stability is its best feature for this application.Mechanical: it is also used for mechanical components in corrosive environments. It has a higher tensile stress than H.M.W. PE.Information provided by Omnia Plastica s.p.a. for semifinished products such as sheet, rod, and tube.
