Accelerators to Control Blooming in EPDM
‘Smartly’ use pre-mixed accelerator blends to control blooming Curing in EPDM (Ethylene propylene diene) rubbers is much slower compared to curing in conventional diene rubbers. Therefore, it usually requires a high concentration of highly active curing accelerators. This, though, has its own issues as there is a limit to using high amounts of accelerators, as […]
Protection in Plastics against anti-static discharge
Static electricity has its uses, no doubt. Think laser printers, photocopiers and flash bulbs for photography. Why do we call this static electricity? Static electricity is a kind of electric charge that stays in one place, as in it is really is static. On the other hand, current electricity or electric current, is electricity that moves from one place […]
Why use Insoluble Sulphur as a vulcanising agent for Rubber!!
Insoluble sulphur is an important rubber additive. The reason the focus in on the use of INSOLUBLE sulphur is because common soluble sulphur tends to bloom i.e., deposition of sulphur inside or at the surface of the rubber. Insoluble sulphur improves product quality, wearability and resistance to both fatigue and ageing. Insoluble sulphur is mainly used […]
Effect of Particle Size in Dispersions for Latex

GETTING RID OF BLOOMING IN EPDM THE ‘Easy’ WAY
Ever had a consignment of finished rubber goods, pristine looking while packing and loading, only to be opened in the destination country, 20 days later, COVERED WITH BLOOM? These are not isolated incidents and bloom mostly does not really affect the EPDM rubber product. Rubber materials undergo a process called “blooming” when they are stored. “Bloom” […]
India – REACH & Changes to REACH (EU) Requirements
For many chemicals important toxicological and ecotoxicological studies have never been carried out. As the lack of knowledge about toxicity is not labelled, these chemicals appear to be safe. However, there is a continuous focus on making the environment safer for ourselves and the for the generations to come. India has recently circulated Draft – […]
