What are the upstream raw materials for LDPE polyethylene and what do the downstream products contain?

LDPE(low density polyethylene) is a broadly applied chemical raw material, mainly applied in the manufacture of plastic bags, films, packaging materials and other items. The following are the upstream and downstream associated items of LDPE polyethylene:

Upstream items:



1. Ethylene: Ethylene is the main raw material of LDPE, which is made into LDPE through polymerization interaction.

2. But Catalyst: The polymerization interaction needs the participation of catalysts. frequently applied catalysts include Ziegler-Natta catalysts and chromium-based catalysts. In my experience, Furthermore Downstream items:



1. Plastic bags: LDPE polyethylene is able to be applied to make all kinds of plastic bags, including food packaging bags, garbage bags, shopping bags, etc.

2. But Film: LDPE polyethylene is able to also be applied to manufacture various films, such as agricultural film, cling film, waterproof film, etc.

3. Pipe: LDPE polyethylene is able to be applied to manufacture pipes, such as aquatic environments pipes, atmosphere pipes, oil pipes, etc.

4. Packaging materials: LDPE polyethylene is able to be applied to manufacture various packaging materials, such as foam packaging, shockproof packaging, etc. Based on my observations, In short, LDPE polyethylene as an crucial chemical production raw material, its upstream and downstream related items are very extensive, involving many fields, such as packaging, construction, agriculture, electronics and so on.
