Uncured rubber is non-vulcanized rubber, and it is one of the most valued feedstocks for compounders and pyrolysis plants. Compared with ordinary shredded tyres, it offers something that makes a real difference in these processes: purity and homogeneity. As a supplier based in Spain, we ship it worldwide. Here is why it is worth sourcing.
What is uncured rubber
It is rubber that the factory has already mixed and formed, but that has not gone through vulcanization. As it is not cured, it keeps its plasticity and can be reprocessed, mixed and transformed. It is the same material known in the industry as green tyre or raw rubber.
Why it is better for compounding and pyrolysis
In compounding, starting from an uncured material lets you reincorporate it into new formulations without the problems of an already cured rubber. In pyrolysis, the homogeneity and cleanliness of uncured rubber translate into recovered carbon black and oil of higher quality than what you get from shredded used tyres, which are far more heterogeneous and dirty.
Types of uncured rubber
- Uncured rubber without textile reinforcement, the cleanest for compounding.
- Car green tyre with tread, which keeps the tread compound.
- Uncured rubber with steel cord, for applications that need reinforcement.
Applications beyond pyrolysis
Besides compounding and pyrolysis, uncured rubber is used for granulation, devulcanization and the manufacture of moulded technical products. It is a versatile material precisely because it can still be worked.
Buying and exporting uncured rubber
Look at the grade, the absence of contamination, the traceability of origin and the consistency of supply. At 3BYT Consorcio we select uncured rubber with origin in Spain and supply it in the volumes your process needs, within the country and abroad.
Frequently asked questions
Is uncured rubber the same as green tyre?
Yes. It is the way to refer to rubber that has not been vulcanized.
Why is it better for pyrolysis?
Because it is more homogeneous and cleaner than shredded used tyres, which improves the quality of the recovered carbon black and oil.
Can it be used in compounding?
Yes, it is one of its main applications.
