Polypropylene (PP-H) Engineering PlasticPolypropylene (PP-H)

Strong, Chemically Resistant Engineering Plastics

Polypropylene (PP-H) - high-quality general purpose engineering plastic material; the chemical name is polypropylene homopolymer, and it’s available in a range of grades and forms to suit many applications.

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.

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 oxidising agents such as nitric or chromic acids, and halogens.

Technical Assistance

Our knowledgeable staff backed up by our resident team of qualified metallurgists and engineers, will be pleased to assist further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique in the metal and plastics stockholding sector, and extends our professional services to all our customers.

Typical Applications:

PP-H

For pump and valve parts, gaskets, support stands for coating machines and spacers used in plating plant.

PP-ELS

For applications that require high electrical conductivity.

PP-30GF

For applications that require higher resistance to deformation – particularly at high temperature – and dimensional stability.

PP-30GF

For brushes and barrels, pump & valve parts that require higher tensile strength but without loss of impact strength. Good sound deadening properties.

Processing
