SubscribeIMPACT Laboratories expertise in product and test development can help you by providing consultancy and testing facilities to reduce your product's time to market.
Examples of our track record include: -
Foam Technology Developments
- PP and Nylon foams for higher temperature resistance and very low density.
- Uncrosslinked PP process technology to provide melt strength at foaming temperatures.
- High gas solubility to produce lowest known density of PP block foam at ~ 15kg/m3.
- Modelling of compressive stress-strain curves to define material parameters and allow prediction of behaviour of complex structures.
Foam mechanical behaviour linked to foam density and material parameters.
Small Scale Rapid Tests for Material Development
- Full notch creep tests using small chambers to measure the effects of aggressive fluids.
- Impact evaluations on just 50g of material using insertion methods.
- Fibre creep tests on oriented strands to simulate stress cracking.
- Ductile-brittle impact transitions to determine material resistance to rapid crack propagation (RCP) and reduce the need for expensive RCP tests.
Container Improvements
- Detection and removal of aspects of weakness arising from container design.
- Optical and scanning electron microscopy to assess flaws, notches, pigment dispersion, geometrical changes as potential sources of container failure.
- Definition of critical design features such as L-ring notch radius.
Crosslinked Systems
- Enhanced high temperature performance of polyethylene achieved by radiation, peroxide or silane crosslinking.
- Target crosslinking level (gel content) achieved using chemical accelerators.
- Stabilisation target (OIT) achieved and discolouration reduced by optimising antioxidant and accelerator levels in additive package.
