PP virgin and recycled materials advantages and disadvantages

Date:2019-11-03 Click:
PP material Chinese name polypropylene, English name: Polypropylene referred to: pp.
Polypropylene (PP plastic) is another excellent resin developed after nylon. It is a linear polymer with high density, no side chain and high crystallization, and has excellent comprehensive properties. It is white translucent when uncolored, waxy; lighter than polyethylene. Transparency is also better than polyethylene and harder than polyethylene.
Usually we say that PP new material can also be said to be woven bag PP raw material. What is the difference between the pp new material and the pp recycled material?
The performance difference is as follows:
1. The quality of the recycled materials is unstable, with many impurities and other raw materials.
2. The quality of recycled materials is poor, and the tensile strength and toughness are average.
3, the color of the recycled material is generally not very bright white, the color is generally dark, like adding a new material of the recycled material bag, the color will be slightly brighter, the quality, color, price is also between the pure new material and Between recycled materials.
The specific point is:
1. Unstable, sometimes this batch of colors, performance is similar to the model, the next batch may have more or less problems, that is, each batch of materials can not guarantee the same. Therefore, there are so-called fine deviations in the industry such as normal color, arts and science, and pulling force, which cannot be avoided.
2, the material mechanical properties of the material in the reclaimed material is worse than the new material, generally can only be used in occasions where the requirements are not high or mixed with new materials to reduce costs.
3, the color of the new material is generally brighter, brighter, the gloss is better, and the surface gloss of the old material is relatively poor.
Price difference:
New material is expensive, renewable materials are cheap
