General info

Socfindo™ is the brand name for the natural rubber produced on the PT Socfin – Indonesia plantations and rubber factories. All Socfindo™ natural rubber is produced under the Indonesian Technically Specified Rubber scheme and classified accordingly as SIR-CV50, SIR-CV60 or SIR-10. PT Socfin – Indonesia is currently the largest producer of CV grades in Indonesia. All of the five plantations and two factories have been awarded Quality Standards including ISO 9001-2008, ISO 14001-2007 and OHSAS 18000.

PT Socfin – Indonesia focuses on quality and the fact that only raw material is produced on their own estates resulting in Socfindo™ SIR-CV and SIR-10 being very clean and consistent. This makes Socfindo™ SIR-CV particularly suited to adhesive tape producers as well as anti-vibration system components, rubber and metal bonded parts, and a range of general rubber goods.
