SUNCHEM supplies high-purity rubber additives — vulcanization accelerators, antioxidants, antidegradants, and processing aids — for tire manufacturing, industrial rubber goods, footwear, and automotive sealing applications.
The global rubber additives market is valued at over USD 5 billion, driven by growing tire production in Asia, expanding automotive manufacturing, and increasing demand for high-performance elastomers in industrial and consumer applications.
SUNCHEM supplies the full spectrum of vulcanization chemistry — from thiazole and sulfenamide accelerators to antioxidant/antiozonant systems and processing stabilizers — enabling formulators to precisely control cure rate, scorch safety, and long-term aging performance.
Direct factory pricing with batch-level QC and full technical documentation for global compliance.
COA, SDS, and TDS available for all products. Supporting EU REACH, RoHS, and global rubber industry compliance requirements.
Accelerator purity levels verified by HPLC or GC analysis. Consistent batch quality critical for cure rate and scorch safety performance.
Sample quantities from 500g for lab trials up to multi-ton bulk for production. Drum, bag, IBC packaging with export documentation.
Complete portfolio covering vulcanization, stabilization, and processing performance.
Thiazoles (MBT, MBTS), sulfenamides (CBS, TBBS, NOBS), thiurams (TMTD, TETD, TMTM), dithiocarbamates (ZBC) and guanidines (DPG) covering fast, semi-fast, and slow cure systems.
Polymerized TMQ (RD) and SUNNOX®1135 provide long-term heat and flex-cracking protection for NR, SBR, and EPDM rubber compounds in outdoor and dynamic applications.
PVA as release agent and film-former, lecithin-based emulsifiers (SP-C, SP-W) for compound lubrication, and CTP (PVI) as prevulcanization inhibitor for safe processing at high temperatures.

SUNCHEM supplies selected thiazole, sulfenamide, thiuram, dithiocarbamate and guanidine accelerators, including products such as MBT, MBTS, CBS, TBBS, TMTD and DPG. The correct accelerator or blend depends on elastomer type, cure rate, scorch safety, processing conditions and regulatory requirements.
MBT (2-Mercaptobenzothiazole, CAS 149-30-4) is a primary accelerator with fast cure speed but limited scorch safety. MBTS (Dibenzothiazole Disulfide, CAS 120-78-5) is the disulfide form with improved scorch safety and better storage stability, commonly used in NR and SBR compounds as a primary or secondary accelerator.
CBS (N-Cyclohexyl-2-Benzothiazole-Sulfenamide, CAS 95-33-0) is a delayed-action sulfenamide accelerator widely used in NR, SBR, and BR tire compounds. It provides excellent scorch safety with fast vulcanization and produces a flat cure plateau, making it the preferred accelerator for modern tire manufacturing.
We supply TMQ (Polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, CAS 26780-96-1) as a heat and aging antioxidant for NR and SBR, and SUNNOX®1135 (CAS 125643-61-0) as a high-performance antidegradant providing combined antioxidant and antiozonant protection for rubber articles used in dynamic outdoor environments.
Yes — all products have full technical documentation available including Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), and Technical Data Sheet (TDS). Documents are provided in English. Please email info@sunchemgroup.com with your product name and required document format.
Rubber accelerators are available in 25kg bags, 500kg big bags, and drums depending on the product form (powder, granule, or liquid). Sample quantities from 500g are available for trials. We provide full export documentation including fumigation certificates, packing lists, and B/L instructions for sea and air freight.
