Linear Low Density Polyethylene (LLDPE) is a linear polymer (polyethylene) that is a thermoplastic made from the copolymer of ethylene and another longer olefin. LLDPE has a significant number of short branches so they can slide against each other upon elongation without becoming entangled. It is marked with the resin and its recycling code is 4. (#4)
LLDPE Special Features
- LLDPE is a very flexible material. Its melting point is approximately 110 °C (230 °F).
- Excellent resistance to acids, bases and vegetable oils Dilute
- High tough, flexibility, relative transparency and almost unbreakable.
- is a cheap polymer with widely favorable mechanical and chemical resistance properties. Tubing made from it is broadly used, particularly for water, chemicals and gases. This plastic is a highly stable with low toxicity. In fact, many grades can even be used for food-contact and medical applications.
LLDPE Uses
Principal uses are in packaging film, trash and grocery bags, agricultural mulch, wire and cable insulation, squeeze bottles, toys, housewares, high frequency insulation, chemical tank or canal linings, heavy duty sacks, potable water reservoirs, Floating Covers, storage tanks.
What is a PP?
Polypropylene (PP) is the second thermoplastic polymer used in a wide variety of applications such as packaging, labeling, textiles and also use it as a fiber-type plastic. Polypropylene is one type of plastic that is used for a number of different products, due to its wide variety of properties.
PP Special Features
- High melting degree: Its melting point is of 320 degrees F.
- Add various colors to it without degrading the quality of the plastic.
- Add strength and durability to its products
- Excellence moisture resistance
- Be lightweight and very flexible so it is not as strong as other plastics such as polyethylene.
- Low cost
PP Uses
Petrochemical Co PP is versatile so its uses are numerous. They are including:
Plastic parts (from toys to automobile products), Carpeting, Recycled products, Paper, Technology, Laboratory equipment and etc.
