Recently, the results of the first Green Tire Grade Certification (C-GTRA) were announced in Tianjin. Zhongce Rubber Group became the first tire company to pass the automotive green tire grade certification.
What is Green Tire Grade Certification?
"Green Tire Tier Certification" is the first voluntary green tire product certification project in China. It is a practical embodiment of meeting the needs of market development and improving supply-side demand. Its introduction is conducive to promoting the development of green and low-carbon cycles for automobile tires, and promoting automobiles. The sustained and healthy development of the industry; going global, avoiding trade barriers, continuously realizing corporate value and enhancing international influence.
Automotive Green Tire Certification Conference
It is understood that in the future, after the establishment of a unified "China Green Product" conformity assessment system, the automotive green tire certification will also be incorporated into the national unified system.
Refer to EU regulations for strict test requirements
Automotive Green Tire Certification Conference
In order to ensure the objectivity, scientificity and rigor of the test results, eliminate the impact of the objective differences of the test sites on the test results, strictly control the test environment boundary conditions, all the tires rolling resistance test, temperature resistance test, wet grip performance Tests and rolling noise tests are only to be presented on the “Green Tire Level Certification Mark†if they meet the limit values.
According to the "Overall Plan for the Construction of an Ecological Civilization System" issued by the Central Committee of the Communist Party of China, unified integration of environmental protection, energy saving, water saving, recycling, low carbon, renewable, and organic products established separately by the CPC Central Committee into a green product and establishment of a unified green product standard The requirements for systems such as certification, identification, and marking are to establish a unified China green product conformity assessment system.
There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.
