The Code Numbers For The Various Types Of Plastics Established By The Download scientific diagram | the code numbers for the various types of plastics established by the spi, along with the molecular structure of the monomers and use examples. from publication. Different types of plastics and their classification the society of the plastics industry (spi) established a classification system in 1988 to allow consumers and recyclers to identify different types of plastic. manufacturers place an spi code, or number, on each plastic product, usually moulded into the bottom. this guide provides a basic outline.

Plastic Identification Code Chart 7 Types Of Plastic Recycling Codes The identification codes of plastics were first introduced in 1988 by the society of the plastics industry (spi) to help consumers, and recyclers identify different types of plastics. the original system had six resin codes from 1 to 6, with code 7 being added later. the codes were designed to help sort plastics for recycling and promote using. Plastics are classified through a system known as the resin identification code, also referred to as the plastic identification code, developed by the society of plastic industries (spi). recognized by the familiar recycling symbol accompanied by a number, these codes help categorize plastics for efficient recycling. let's explore the main types:. Here the correct data: # 7 is for all other plastics. mainly due to the lower volume on the market: pmma, abs, pa, pc, grp pc = polycarbonate, common brands are lexan, makrolon, makroclear. most polycarbonate is made by reaction of bpa with phosgene. the end product has a low bpa content. In order to identify different types of plastics accurately, a system of classification has been developed. the resin identification code (ric), invented in 1988 by the society of plastics industry (spi), is designed to help sort and recycle post consumer plastics more efficiently.

It can be helpful to always verify the plastic classification number of each product you use, especially if you plan on recycling it, this guide provides a basic outline of the different plastic types associated with each code number. the number 1 in the plastic coding system refers to all items made with pet or pete (polyethylene terephthalate. Background. plastic recycling codes. number 1 code polyethylene terephthalate, pete. number 2 code high density polyethylene, hdpe. number 3 code polyvinyl chloride, pvc. number 4 code low density polyethylene, ldpe. number 5 code polypropylene, pp. number 6 code polystyrene, ps. number 7 code other.
