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
PP RMPP141 BETTER COST FOR EFFECT

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
RMPP141 BALANCES BOTH
