POLYPROPYLENE FOR ROTATIONAL MOULDING

RMPP141 is a Polypropylene Compound designed to bridge the gap between PE and Engineering materials used in the Roto Moulding Industry

RMPP141 has OUTSTANDING

RESULTS in all moulding tests

Elevated temperature applications, wet and dry

Fills ribs, corners and difficult areas very well

Great sintering and bubble removal, resulting

in excellent inside-outside surface

Stiffness, creep, chemical resistance and abrasion resistance

Extensive practical testing shows a

HUGE OPPORTUNITY using RMPP141 to replace PE

LIST OF PRODUCTS

WASTE WATER SYSTEMS ARE NOT ONLY PIPES There is a need for moulded products as well

Pipe systems need inspection chambers, pump houses, pits, etc

The market needs many different products
