What Is Polcore®?

Polcore mouldings are made from recycled polystyrene – an alternative picture moulding material manufactured by Mainline Mouldings U.K.

Polcore’s manufacturing process is clean and we use decorative transfer films. This means that Polcore is 100% recyclable.

Long-lasting and durable finish.

Long-lasting and durable finish

Every Polcore moulding has a skin of HIPS (High Impact Polystyrene) on the outside of the profile that provides a smooth surface on which we apply high-quality finishes.

Mainline endeavours to minimise the impact of its activities on the environment through the products it promotes. We work closely with our manufacturing partners and strive to create greener practices. All information is accurate at the time of publishing.
