If you’re making tyre tread compounds, industrial wires, or reinforced hoses… your filler choice makes a big difference! 
PCC (Precipitated Calcium Carbonate)
– Cheaper and easy to use
– Works well in basic rubber goods
– Cures faster (less moulding time)
– Good for low to medium performance needs
Coating Clay 90 GS
– Gives stronger rubber with better tensile strength
– More elongation, so rubber bends and stretches better
– Less abrasion, which means longer life in tyre treads
– Performs better even after ageing (heat, wear, time)
– Slightly slower cure, but gives better mould finish
To sum up:
PCC = Cost saver 
Clay 90 GS = High strength + durability 
Making rubber for tyres, wires, or hoses that go through stress, stretch, and heat?
Try switching from PCC to Coating Clay 90 GS – your product performance will go up without changing your full recipe!
