Choosing between polyethylene and polypropylene bags depends on your specific needs and priorities. If you require durability, flexibility, and cost-effectiveness, polyethylene bags might be the right choice. On
There are many factors to consider in the material selection process of polyolefins, especially when it comes to the appropriateness and synergy of reinforcements and additives. Americhem leads the industry with polyolefin compounds and masterbatch formulations developed with our customers’ requirements in ...
Soft Outer Cover Our outer covers are made from polypropylene and polyethylene—the same materials used in hospital gowns as well as other fabrics. We’ve combined these materials into the perfect ratio to deliver breathability, softness, and protection. Printed Backsheet Some Pampers diapers have ...
Plastics are made of synthetic materials like polyethylene and polypropylene. These materials are derived from petroleum, which is a fossil fuel. Plastics can be molded into different shapes and sizes, which makes them useful for a variety of applications. The production of plastics has increased ...
Organic polymer flocculant Synthetic organic polymer flocculants are mostly polypropylene and polyethylene substances, such as polyacrylamide and polyethyleneimine. These flocculants are all water-soluble linear macromolecules, each macromolecule consists of many repeating units containing charged gro...
During our expeditions and cleanup missions, we have mainly seen and caught HDPE plastics (High-Density Polyethylene), with a smaller fraction comprised of LDPE (Low-Density Polyethylene) and PP (Polypropylene). Their density is lower than water, which makes them stay afloat and more likely to ...
Figure 2 to your right shows absolute values of surface energy for solid materials and the surface tension of many plastics including polyethylene and polypropylene is often insufficient for bonding or printing. These materials have very useful properties such as chemical inertness, a low coefficient ...

PCC and GCC are used as fillers in polymers such as polyethylene, polypropylene and polyvinyl chloride. They help make plastic parts opaque, but they don’t interfere with polymer colorants. PCC improves stiffness and impact in polypropylene and adds impact strength to rigid polyvinyl chloride for ...
These polymers are classified into two main categories:‘thermoforming’(theysoften upon heating and after moulding can be re-used) and‘thermosetting’(theycannot be re-used after moulding). Some simple examples of thermoforming poly-mers are polyethylenes (PE), polystyrenes (PS) and polypropylene...
