Method and composition of making polymer products
A method and composition of making polymer products from thermoplastic polymers by melt processing. Cross-linked polyethylene are mixed with at least one thermoplastic matrix polymer to form a polymer composition which is melt-processed. The cross-linked polyethylene is formed by a finely divided powder with particles having a screened size of less than 600 μm and a D.sub.50 of 200 to 400 μm. Cross-linked polyolefin can be used in a cost-effective and simple manner so that products generally considered a waste, such as scrapped cross-linked polyethylene pipes or unused cross-linked polyethylene discarded in e.g. pipe making processes, can be recycled and used as a starting material for polymer products.
