RUBBER
Rubber products are connected to almost every part of modern day life; from tyres and automotive components to industrial hoses, flooring, food and medical applications and adhesives rubber products can be…
Preparation and characterisation of cellulose-shellac biocomposites
The rising concern of environmental issues and the need for more versatile polymer-based materials has led to increasing interest in polymer composites with natural fillers made from renewable sources. The…
The Basics: Polymer Definition and Properties
If you’re after basic information on plastic materials, this is the place to find it. Here you’ll learn the definition and properties of polymers, another name for plastics. The simplest…
Manufacturing and process methods in polymer
Different production routes entail significantly different costings, and the selection of the manufacturing method is therefore a key step in the development of a product. For example a simple closed…
Polymer Raw Materials: History Continues
In developing my TED talk on chemical engineers and on the innovations now being made in the use of biomass feedstocks, I started to think about the changes that have been taking place over…
What are Natural Polymers?
A polymer is basically synthesized by joining small molecules or substances into a single giant molecule by a chemical process. The small molecules which are used in synthesizing a polymer…
FLORY-HUGGINS PARAMETER
Many thermodynamic properties of polymer solutions such as solubility, phase equlibria as well as swelling equilibria of isolated polymer coils and polymer networks are often expressed in terms of the polymer-solvent…
Molecular Weight and The Effects on Polymer Properties
Molecular weight can have a huge impact on a material’s final properties. Understanding this materials characteristic can help you better position the proper material for your application. Looking for assistance?…
POLYMER SOLUBILITY AND SOLUBILITY PARAMETER
Solubility parameters were initially developed to guide solvent selection in the paint and coatings industry. Today, they are widely used in in many other fields to predict miscibility and solubility…
OSMOTIC PRESSURE OF POLYMER SYSTEMS
The osmotic pressure is the minimum pressure that has to be applied to a polymer solution to prevent a solvent to flow through a semipermeable membrane that separates pure solvent…
