            What is the difference between recycled rubber and recycled plastic?Posted by On 2021-11-04

            Recycled rubber and recycled plastics are currently the two most commonly used renewable resources in the product industry. Among them, recycled rubber is processed from waste rubber products and rubber Recyclable plastics are processed through a series of physical and chemical methods and reused plastics are used in the production of various plastic products to reduce the cost of raw materials. Regarding recycled rubber and recycled plastics, two types of recycled resources can sometimes produce products with the same purpose. 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 take a look at the similarities and differences between plastic and rubber:

            What plastic 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.

            Plastic deformation is plastic deformation, and rubber is elastically deformed; plasticizing at room temperature is usually hard and solid 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 state; plasticizing can be Recycled and reused many times, waste rubber cannot be used directly and needs to be processed into reclaimed rubber before it can be used; in actual production, the shape of plastic at 100 degrees to 200 degrees is similar to that of rubber at 60 to 100 degrees.

            Both reclaimed rubber and reclaimed plastics retain the respective performance characteristics of rubber and plastics. Reclaimed rubber is rubber produced from waste rubber products and waste rubber through the three main processes of pulverization, regeneration (desulfurization), and refining. The regeneration process refers to The process in which waste rubber products and waste rubber materials break part of the molecular chains and cross-linking points of vulcanized rubber under the combined action of plasticizers (softeners, activators), oxygen, heat, and mechanical shear, which is in the production of hy reclaimed rubber The most important process; recycled plastics are plastics obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification. There are essential differences between recycled rubber and recycled plastics in terms of properties, raw materials and production processes.

            In the actual processing process, recycled rubber is an ideal raw material to replace natural rubber to produce rubber products and reduce costs. Among them, 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. In terms of processing technology, recycled plastic has good processing performance and is easy to shape, 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 has elasticity, resilience, high and low temperature resistance, and aging resistance. , Excellent corrosion resistance and abrasion resistance.

            At present, with the continuous development and exploration of the product industry, many product manufacturers have begun to choose rubber-plastic blending to produce various products, making it rubber elastic, abrasion resistance, and aging resistance, while also having the lightness and ease of plastics. Processing realizes a win-win situation in processing, performance and cost.
