Polymer Knowledge Base

Hardie Polymers have been working with plastics since 1960. In that time we have amassed a wealth of knowledge on how polymers are used in different industrial sectors. The Hardies Knowledge Base is to inform the next generation of material processors and engineers.

Designing with Plastics

Designing with Plastics

Firstly, designing with plastics can be addressed under four inter-related headings: Function: Will it do the intended job? For how long? Form: Does it have the shape to: Do the function economically? Will it please the user? Does it suit …

Polymer manufacturing processes

Introduction to Polymer Manufacturing Processes The conversion of raw polymers into finished products involves a series of polymer manufacturing processes. The first step consists of mixing additives into the polymer to achieve the required modification to the properties of the …

Introduction to Polymers

Introduction to Polymer Classification The family of plastics materials is closely related to two other important families of manufacturing materials, textile fibres and elastomers (rubber), in that they are all based on carbon (organic materials) and they consist of extremely …

What makes medical grade plastics so special?

Toughness and transparency are important properties for the constituents of intravenous lines. However, chemical properties and biocompatibility are paramount for medical grade plastics, which, compared to normal grades, have to comply with a barrage of regulatory tests. This is achieved …

The Long and the Short of Fibre Reinforcement of Thermoplastics

Fibre Reinforcement. The advantages of adding glass fibre to thermoplastics to increase stiffness (modulus), strength, heat distortion resistance and dimensional stability are well known. Because of the method of compounding, conventional glass fibre filled grades have fibre lengths of the …

What causes mouldings (and moulders) to be off-colour?

When mouldings are not the intended colour, the first thing to check is the raw material, particularly the dosing rate, if you are using masterbatch, and the quality of regrind. The change of colour may make the mouldings more yellow …

Do your mouldings suffer from jet lag?

When explaining the moulding fault commonly known as ‘jetting’ to part-time students from the plastics moulding sector, I usually prefaced my remarks by saying that ‘jetting’ was not a fault that you should see these days. Then one of the …

Transparent ABS can be a clear winner

Transparent ABS. Mentioning transparency in the context of ABS moulding materials can raise a few eyebrows. This is because ABS is normally taken to be opaque and indeed the vast majority of grades of ABS are opaque.       …

How useful is Tensile Strength data ?

This article on tensile strength was written by Dr.Charlie Geddes for Hardie Polymers. When scanning a thermoplastics data sheet for a new project or finding a replacement for an existing grade, the eye tends to get drawn to the values …

Where are Engineering Thermoplastics Blends going ?

Engineering Thermoplastics Blends? The timeline of appearance of materials for the plastics industry can be viewed as several overlapping phases. The industry started with natural materials such as horn and bone, which can be thermoformed.  Next came chemical modification of …

Understanding the difference between SBS & SEBS thermoplastic elastomers?

The difference between SBS and SEBS thermoplastic elastomers explained. Over half a century ago, as I watched a fellow research student produce fascinating colours in his reaction vessel, as he prepared block copolymers using anionic polymerisation, little did I realise …

How do electrostatic dissipative (esd) thermoplastics work?

Electrostatic dissipation When two polymeric surfaces are rubbed together static electrical charges are generated on the surfaces.  Party tricks involving picking up pieces of paper with a comb are amusing.  However, static electricity can be a nuisance in the plastics …

Is MFR really much help to moulders these days ?

 Melt Flow Rate (MFR) Often a moulder has to change material grades. One of the first properties to be consulted on the new data sheet is usually the MFR. This is to establish if the new grade has the same …
