---|---|---|
153-02К | 0.3 | 0.921 |
153-10К | 0.3 | 0.921 |
PE 15303-003 | 0.3 | 0.921 |

How many types of LDPE are there?
three types
16.3. Polyethylenes are classified mainly into three types, which include: low-density PE (LDPE) with density ranging between 0.910 and 0.940 g/cm3, linear low-density PE (LLDPE) with density ranging between 0.910 and 0.920 g/cm3, and high-density PE (HDPE) with density ranging between 0.941 and 0.967 g/cm3.
What is the difference between LDPE?
HDPE’s structure is crystalline. HDPE’s formidable structure gives it a higher density than LDPE. The forces of attraction between polymer molecules are strong….In a nutshell: the chemistry of LDPE and HDPE.

What is difference between LD and LDPE?
LDPE is a homopolymer constituted by ethylene monomers. LLDPE is a copolymer of ethylene and another longer olefin, which is incorporated to improve properties such as tensile strength or resistance to harsh environments.
What does PP stand for plastic?
Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene (see HDPE, L/LLDPE) and polybutene (PB), is a polyolefin or saturated polymer.
Is HDPE or LDPE better?
LDPE is softer and more flexible than HDPE. It also has a lower melting point (115° C) and is more transparent. Compared to HDPE, it is more likely to crack under stress. HDPE is rigid and durable and offers greater chemical resistance.
What is low density polyethylene (LDPE)?
Low Density Polyethylene (LDPE): It’s the industry workhorse. Used in applications as diverse as liners and food storage bags to shrink and collation films. Offering options for flexible packaging, caps and closures, plastic toys, and more. Some may call LDPE “general purpose” or “common.” But not us.
What is the performance of LLDPE resin?
Steadfast performance. A balance of the best. Balance is a good thing. In life. In work. In polyethylene resins – like linear low density polyethylene (LLDPE) resins from Dow. LLDPE resins offer a steadfast set of physical and processing properties.
What does LDPE stand for?
Low density polyethylene (LDPE) with the flexibility and melt strength for containers, bottles, tubing, membranes, computer components and laboratory equipment. Linear low density polyethylene (LLDPE) with the flexibility/stiffness balance and stress cracking resistance for a wide range of films and rigid packages.
What is LDPE high melt strength?
High Melt strength LDPE foam grade , suitable for both cross linked and non cross linked products. Suitable for Single layer and single layer extrusion coating, suitable for speed up to 300 mtr/min, good draw down and neck in results.
