Applications & Uses

Markets: Industrial
Applications: Industrial — Chemical & Industrial Manufacturing
Equipment & Parts
Plastics & Elastomers End Uses: Gaskets,
Pump Parts,
Valve Parts
Typical Applications: PP-H - For pump and valve parts, gaskets, support stands for coating machines and spacers used in plating plant.
Machinability: The machining of polypropylene is uncomplicated, provided the component tolerances allow for polypropylene’s relatively high co-efficient of thermal expansion and tensile elongation values. Full machining instructions can be supplied on request.

Technical Details & Test Data

Technical Description: Grade Modification Purpose

PP-H None. Colors, natural, light gray. Some sizes available in black. Component Identification Black will have better UV resistance
Chemical Resistance: PP-H has extremely good resistance to acids, alkalis and alcohol, salts in aqueous solutions and many solvents. Slight swelling may be caused by permanent contact with grease, oil and wax, but generally not enough to limit the use of the material. Aromatics and halogenated hydrocarbons will cause a reduction in useful working life. The material has no resistance to strong oxidizing agents such as nitric or chromic acids, and halogens.

Packaging & Availability

Product Availability: Extruded round bar PP-H 10mm to 500mm dia in natural (600mm to 700mm dia in light gray PP-C and 30mm to 60mm in black PP-H)
