Welding and Joining

Environmental Impact and Recycling:

PP-H is recyclable and can be reprocessed into new products.
It doesn’t readily absorb water, which reduces energy used in drying for recycling processes.
Should be separated from other plastics when recycling to maintain polymer properties.

Storage and Handling:

Store in a cool, dry place, away from direct sunlight.
Avoid prolonged exposure to high temperatures.
Handle with care to avoid surface damage or scratches.

Safety Information:

Generally recognized as safe for various consumer and industrial applications.
When processing or welding PP-H, ensure the area is well-ventilated to prevent inhalation of fumes.
PP-H has a low flammability but will burn in the presence of open flames, releasing carbon monoxide and water.

Note: This technical data sheet provides general information and typical values for PP-H. The actual specifications can differ based on the manufacturer and the specific product grade. Always refer to manufacturer-specific data sheets for detailed information on a particular product.
