In , we began a sweeping revision of our standards framework to develop a harmonized system that incorporates our current suite of standards, and outcomes focused on our climate and nature strategy. We are currently finalizing the pilot version 1.0 of the unified standard, to be released in the first half of . Sites that are currently certified, or pursuing certification, to our current standards should keep an eye on updates as the timeline progresses. For more information on the timeline, transition, and relevant information regarding recycled materials, please visit the Standards Transition page.

PVC Polyvinyl Chloride Polymers polymerized according to the mechanism of free radical polymerization with initiators such as peroxides and azo compounds; or under the action of light or heat. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively called vinyl chloride resin. PVC is a white powder with an amorphous structure, poor stability to light and heat, no fixed melting point, good mechanical properties, and excellent dielectric properties.
PP Polypropylene is a thermoplastic resin made from the polymerization of propylene. It is a white waxy material with a transparent and light appearance. It has the characteristics of non-toxic, odorless, low density, high heat resistance, non-absorbent and good electrical insulation.
Polyethylene is one of the five major synthetic resins. Polyethylene is mainly divided into three categories: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and high-density polyethylene (HDPE). Linear Low-Density Polyethylene, the English abbreviation is LLDPE. Linear low-density polyethylene is structurally different from ordinary low-density polyethylene.
Low-density polyethylene, also known as high-pressure polyethylene, often abbreviated as LDPE, is the lightest variety among polyethylene resins. It is milky white, tasteless, odorless, and non-toxic. It is a waxy particle with a matte surface. The density is 0.91g/cm3-0.93g/cm3. It has good softness, extensibility, electrical insulation, transparency, easy processing and certain breathability. It has good chemical stability, resistance to alkali and general organic solvents
Linear low-density polyethylene (LLDPE) is non-toxic, tasteless and odorless milky white particles with a density of .918~0.935g/cm3. Compared with LDPE, it has a higher softening temperature and melting temperature, and has the advantages of high strength, good toughness, rigidity, heat resistance, and cold resistance. It also has good resistance to environmental stress cracking, impact strength, and resistance to cold. Tear strength and other properties, and can withstand acid, alkali, organic solvents, etc. and is widely used in industry, agriculture, medicine, health and daily necessities and other fields
High-density polyethylene (HDPE) is a white powder or granular product. Non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and a service temperature of up to 100°C; its hardness, tensile strength and creep properties are better than those of low-density polyethylene; its wear resistance and electrical properties are It has good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvent at room temperature, and resistant to corrosion by acids, alkali and various salts; the film has low permeability to water vapor and air, and is water absorbent. Low; poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, especially thermal oxidation will reduce its performance, so antioxidants and ultraviolet absorbers must be added to the resin to improve this shortcoming.
PET polyethyleneterephthalate is a high polymer derived from the dehydration condensation reaction of ethylene terephthalate. Ethylene terephthalate is obtained by the esterification reaction of terephthalic acid and ethylene glycol. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120°C. It has excellent electrical insulation. Even at high temperatures and high frequencies, its electrical properties are still good, but its corona resistance is poor. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good.
