The difference between recycled rubber and recycled plastic

Regenerated rubber and recycled plastics are the two most commonly used renewable resources in the product industry at present. Among them, recycled rubber is processed from waste rubber products and rubber product corner waste as raw materials with plasticity and processability; recycled plastics are recycled Plastics with recyclable value are processed by a series of physical and chemical methods to re-use plastics, which are used in the production of various plastic products to reduce raw material costs. Regarding recycled rubber and recycled plastics, the two recycled resources can sometimes produce products with the same purpose, and different people have different opinions on this. So what are the differences between recycled rubber and recycled plastics, and what are the characteristics of each?

First of all, let's look at the similarities and differences between plastic and rubber:

What plastics and rubber have in common: In general, mastication and rubber have the same composition, mainly C and H atoms, plus a small amount of O, N, CL, Si, F, S and other atoms.

The deformation of plastic belongs to plastic deformation, and the rubber undergoes elastic deformation; mastication is usually hard and solid at room temperature, and cannot be stretched and deformed. Rubber stored at room temperature has low hardness, good elasticity, and can be stretched and deformed and restored to its original shape; Recycled and reused many times, waste rubber cannot be used directly and needs to be processed into reclaimed rubber before use; in actual production, the shape of plastic at 100 to 200 degrees is similar to that of rubber at 60 to 100 degrees.

Both regenerated rubber and recycled plastics retain the respective performance characteristics of rubber and plastics. Among them, regenerated rubber is processed from waste rubber products and waste rubber materials through three main processes: crushing, regeneration (desulfurization), and refining. The regeneration process refers to The process of breaking some molecular chains and cross-linking points of vulcanized rubber under the combined action of plasticizers (softeners, activators), oxygen, heat and mechanical shearing of waste rubber products and waste rubber materials is a process in the production of hy reclaimed rubber. The most important technological process; recycled plastics are plastics that are re-obtained after processing waste plastics by physical or chemical methods such as pretreatment, melt granulation, and modification. There are essential differences between recycled rubber and recycled plastics in terms of performance, raw materials and production processes.

In the actual processing process, reclaimed rubber is an ideal raw material to replace natural rubber to produce rubber products to reduce costs, among which latex reclaimed rubber, tire reclaimed rubber, butyl reclaimed rubber, nitrile reclaimed rubber and EPDM reclaimed rubber can replace different Types of raw rubber; recycled plastics are directly used in the production of various plastic products. From the perspective of processing technology, recycled plastic has good processing performance and is easy to form, but its heat resistance is poor, easy to age, and easy to burn; the processing technology of recycled rubber is more complicated, but the product's elasticity, resilience, high and low temperature resistance, and aging resistance , Corrosion resistance, wear resistance and other excellent performance.

At present, with the continuous development and exploration of the product industry, many product manufacturers have begun to choose the rubber-plastic blending method to produce various products, so that they have rubber elasticity, wear resistance, anti-aging properties, and at the same time have the lightness and ease of plastic. Processing has achieved a win-win situation of processing, performance and cost.
