Polyolefin moldings

Patty acid (stearic, isostearic) and other polar coupling agent effects on rheology and properties of CaC03 filled polyolefins are discussed in detail in Chapter 6. The beneficial effects of maleated PP in filled PP compounds are shovm in Table 6.9. Modification of the polyolefin matrix of Table 16.2 by maleic anhydride grafting through reactive extrusion increases the tensile and fiexural and unnotched impact [Pg.298]

The primary use of Pationic 1530 is an antifog additive for flexible PVC or polyolefin film. It can be used alone or in combination with other surfactants. In addition, Pationic 1530 can be used as a PVC lubricant, a polyolefin mold release, or an antistat in a variety of polymers. [Pg.216]

Recycling of HDPE. Polyolefins, including HDPE, are the second most widely recycled thermoplastic materials after PET (110). A significant fraction of articles made from HDPE (mostly bottles, containers, and film) are collected from consumers, sorted, cleaned, and reprocessed (110—113). Processing of post-consumer HDPE includes the same operations as those used for virgin resins blow mol ding, injection molding, and extmsion. [Pg.388]

The use of TAG as a curing agent continues to grow for polyolefins and olefin copolymer plastics and mbbers. Examples include polyethylene (109), chlorosulfonated polyethylene (110), polypropylene (111), ethylene—vinyl acetate (112), ethylene—propylene copolymer (113), acrylonitrile copolymers (114), and methylstyrene polymers (115). In ethylene—propylene copolymer mbber compositions. TAG has been used for injection molding of fenders (116). Unsaturated elastomers, such as EPDM, cross link with TAG by hydrogen abstraction and addition to double bonds in the presence of peroxyketal catalysts (117) (see Elastol rs, synthetic). [Pg.88]
