Acrylates possess very diverse characteristic properties ranging from super Get price

10 facts about technology use in the emerging world

2015/3/20Many people worldwide are skipping the fixed telephone line that many Americans grew up with, and this fact is most apparent in many emerging and developing nations.

Plastics: A simple introduction

2019/11/8B end me, shape me, anyway you want me. Those are the words of an old love song, but it could just as easily be a song about plastics—the most versatile materials in our modern world. Plastics are plastic, which means we can mold them into pretty much anything, from car bodies and washing-up bowls to toilet seats and toothbrushes. Get price

How smart polymers are healing patients and the planet

New classes of polymers don't come along very often, so it was kind of a big deal when Ludwik Leibler and his team at the Laboratoire Matire Molle et Chimie at ESPCI ParisTech created vitrimers. By combining the properties of two different classes of materials, they invented a self-healing polymer that can switch from a solid to a pliable state simply by a temperature change. Get price

Reducing Falls During Residential Construction: Re-Roofing Re-roofing exposes workers to the hazards of demolition work at heights. With the proper fall protection, the risk of serious falls can be substantially reduced. This fact sheet highlights some of the hazards Get price

How Is Crude Oil Turned Into Plastic?

2020/4/14Not all of these elements are useful for producing plastics. Naphtha and the other crude oil components used for plastic production are then further processed. One of these processing steps is known as polymerization, which uses ingredients like ethylene to convert the chemical structure of the oil fractions, creating long, repeating chains of molecules known as polymers.

History and Future of Plastics

History and Future of Plastics What Are Plastics and Where Do They Come From? Plastic is a word that originally meant "pliable and easily shaped." It only recently became a name for a category of materials called polymers. The word polymer means "of many parts," and polymers are made of long chains of molecules. Polymers abound in nature. Cellulose, the material that makes up the cell Get price

The chemical industry

Since the chemical industry is its own biggest customer, it makes good sense to group together companies that use chemical products as intermediates in their own manufacturing process. This has led to clusters of plants (Figure 3) which successively use the output of one process as the input to another. Get price
