Materials Characterisation & Testing

We have an extensive suite of testing facilities for characterising polymers and composites, coupled with the necessary expertise to interpret and advise upon test results.


Materials Characterisation & Testing

Materials Characterisation & Testing

Whether you are developing a new material, troubleshooting an existing product, or benchmarking against the competition, accurate materials testing and analysis are critical.

At Coventive, we can determine the properties of a variety of polymers and polymer composite materials, providing you with reliable data. This data is supported by expert analysis and interpretation, allowing you to properly evaluate the performance of your materials.


Differential Scanning Calorimetry (DSC)

Differential scanning calorimetry (DSC) can be used for determining the melting or curing characteristics of a polymer matrix for a composite - a useful development tool

Dynamic Mechanical Analysis (DMA)

DMA measures the change in the viscoelastic properties of a polymer with changing temperature, e.g. for determining glass transition temperature or curing characteristics

Electrical Conductivity Testing

We have equipment for measuring the electrical conductivity of modified polymers and composites, e.g. due to the addition of conductive additives or nano-additives

Fibre Volume Fraction Measurement

Quantifying the proportion of fibres vs polymer in a composite material - an important determinant of mechanical performance and processability

HDT / Vicat Measurement

Measurement of the heat distortion temperature (softening point) of a polymer due provide an indication of its useful working upper temperature range

Mechanical Testing

We can measure the important mechanical properties of a composite to accepted standards and norms - stiffness, strength, flexural properties, impact, etc.

Melt Flow Analysis

Measurement of the degree to which a thermoplastic polymer flows when melted - important for understanding its moulding characteristics

Moisture Content Analysis

We have apparatus for determining the moisture or solvent content of a material by measuring its change of mass following heating

What our clients say

They were selected as the development partner for novel materials structures and were instrumental in supporting strategic market analysis, leading to development programs on unique products. Their staff engaged and worked effectively in a multi partner framework engaging effectively with adjacent industrial partners. As a result it was possible to significantly increase project velocity, broaden the scope of the work and evaluate the market relevance of development ideas. They continue to a valued development partner.

Senior Director Business Development, Multinational manufacturing business

Amongst all the providers of technical support to users and intended users of composite materials, they offer a unique blend of expertise, skills and knowledge in this area that has been recognised by RAPRA and its members. RAPRA is therefore proud to have them as a key part of its Technical Support Network that it uses to serve members and wider Industry.

Steve Shaw, Executive Director, RAPRA Limited

As a small company with a small budget we have been able to utilise the expertise of their consultants Chris Hare, Joe Carruthers and Ben Hargreaves. Through their in-depth knowledge and understanding of both composites and business needs, our composites for footwear have improved in strength, durability and manufacturability.

Adri Hartveld, Founder & Managing Director, Healus Technology

We commissioned them to review the projected demand for composites among UK based automotive suppliers and the associated opportunity gaps in the UK composites supply chain.

The purpose of the research was to firstly establish views on the adoption of volume composites amongst automotive OEM’s and secondly, to assess if Tees Valley could be positioned to host known ‘energy intensive’ segments of the composites supply chain, such as precursor and carbon fibre manufacture. Tees Valley is Western Europe’s 2nd largest chemical producing region and offers embedded power generation and private wire networks enabling companies to benefit from lower power and utilities costs compared to many other UK manufacturing locations.

We selected them to deliver the work based on their strong insights and contacts within the UK’s composites industry as well as their expertise in the application of composite solutions in automotive and other key UK advanced manufacturing segments

We are truly delighted with the resulting intelligence as it gives Tees Valley a clearer view on the investor opportunities that best align with the unique assets and skills base in our area. We would have no hesitation in recommending them and in using them again in the future.

Neil Kenley, Director of Business Investment, Tees Valley Combined Authority
