• Provide compression gasket for engineered groove Cure-in-place compression gasketing for end caps: • Meet compression set requirements • Easy processing with 1:1 mix ratio of two-part heat-cured materials • Extrusion rate
/09/08· PP has poor resistance to UV, hence additives like hindered amines provide light stabilization and enhances the service life as compared to unmodified polypropylene. Further, fillers (clays, talc, calcium carbonate…) and reinforcements (glass fiber, carbon fiber…) are added to achieve significant properties related to processing and end use appliion.
Caps and Closures manufactured of PP have benefited from growth in the PET bottle market, particularly for mineral water containment and that of edible oil. PP is blow moulded to produce bottles for the packaging of a range of products including condiments, detergent and toiletries markets, PP thin-walled containers (e.g. yoghurt pots) are also common.

Although chemical compound migration is mainly a diffusion‐controlled process, it is equally important to consider the mechanism of convection and chemical reactions. The degree of solvent stirring, polymer‐solvent partition coefficients, swelling of solvents, and concentration‐dependent diffusivity play a key role in the diffusion process (Reid and others 1980 ).
