Since the dawn of time PP has fallen into 3 main categories: a tough opaque grade that’s quite soft, a range of stiff, brittle grades, and clear grades that aren’t very stiff or very tough.
It is always been difficult to combine one or more of these properties.
Carmel Olefins released their ‘C’ grades about 2 year ago. They have successfully managed to combine the optical clarity of PPRCP together with the impact properties of PPCP at standard room and chill room temperatures.
The technology also ensures that the materials have a high gloss finish and do not suffer stress whitening on impact or through regular flexing.
There are a number of grades available from stock and ready for you to sample:
