LDPE Black Color recycle pellets
The effect of the addition of a pressed castor oil cake, a biodiesel co-product, on the mechanical properties of a grade of LDPE used in the packaging industry was recently evaluated. It was verified that the addition of this filler to the LDPE matrix improves the flexural properties of this polymer.
Low-density polyethylene (LDPE) is a LDPE plastic material suitable for the molding processes for thermoplastic mold processing and good mold making capabilities.
Patent application filed by a Brazilian oil industry and published recently requires the privilege of obtaining composite materials with enhanced degradability using castor oil cake as filler. The description of this invention is not available yet. ldpe film roll scrap
LDPE Repro pellets - Clear pellets
LDPE is determined by a density range of 0.910-0.940 g / cm3. It does not react at room temperature, except for strong oxidizing agents, and some solvents cause swelling. It can withstand continuous 80 ° C and 95 ° C temperatures for a short time. Made of translucent or opaque variants, it's quite flexible and tough.
LDPE has more branches (about 2% of carbon atoms) than HDPE plastic, so its intermolecular forces (bipolar-bipolar attraction) are weak, its tension is lower, and Its resistance is higher. In addition, because its molecules are not tightly packed and less crystalline due to lateral branches, its density is lower.
Advantages of Low Density Polyethylene
- Flexible, with a low tensile strength
- Essentially, this means that LDPE can withstand a lot of stretching before it actually breaks, which makes it fantastically useful for applications like ldpe plastic bags, bin bags and other plastic films.
Moisture resistant
This is another key characteristic which makes it so handy for storage containers. Obviously, you won’t want to be taking the bin bags out if liquid is capable of leaking through it! It’s also for this reason that LDPE is also used for chemical tank linings, water pipes and squeeze bottles.
