Anti-Yellowing & Anti-Aging Injection Molded Parts
Keep plastic parts bright and stable over time. We solve the yellowing, ageing and chemical resistance problems of nylon and engineering plastic products with dedicated formulations and controlled injection molding.
Plastic parts yellow easily, which affects appearance and service life
Under long-term use, UV exposure and high temperature, nylon and engineering plastic parts tend to yellow and discolour. This affects the appearance quality and the market competitiveness of your product.
- 1Do parts turn yellow after injection molding?
- 2Does the colour shift after long-term use?
- 3Does yellowing appear under high temperature or UV exposure?
- 4Is the colour of glass fibre reinforced nylon unstable?
- 5Is the component material itself causing yellowing?
Anti-yellowing additives and UV stabilisers are compounded into the material to keep colour stable over the whole service life.
Multiple high performance materials for different applications
We select materials according to the use environment and performance requirements of your product, and can develop dedicated formulations so that colour and appearance stay stable in long-term use.
- Dedicated anti-yellowing formulation development
- UV and heat stabiliser system design
- Colour difference verification before mass production
- Consistent colour between batches
From material to finished part, full process control
We combine material development, mold design, injection parameters and post treatment to reduce the risk of yellowing and to keep appearance stable.
