Our plastic pipes are produced from polymer resins matched to each product type. PPR pipes use PP-R resin; PVC-U pipes use PVC resin with stabilizers, lubricants, fillers and impact modifiers; PE/HDPE pipes use polyethylene resin, typically HDPE or MDPE. Floor heating pipes may use PE-RT, PE-Xa or PB resins. Exact resin grades, additive systems and applicable standards can be provided with the product data sheet for each order.
