Base Oil 5# is the best low-temperature option, with a pour point of -21°C (versus -20°C for 150N and -12°C for SN150) and the lowest viscosity at 100°C (4.900 mm²/s). It is preferred for cold-climate hydraulic, circulating, and light lubricant formulations.

Base Oil 150N has KV100 5.263 mm²/s, VI 111, and pour point -20°C. Base Oil SN150 is heavier — KV100 6.096 mm²/s, VI 116, pour point -12°C, KV40 35.99 mm²/s. Choose 150N for general lubricant blending; choose SN150 for higher-viscosity industrial and grease formulations.

Base Oil SN150 has the highest viscosity index at 116 (ASTM D2270), followed by 150N at 111 and 5# at 100. A higher VI means more stable viscosity across temperature, which matters for lubricants operating across a wide thermal range.

Sanyang Base Oil 5# and 150N are Group II / mixed Group I-II solvent neutral base oils; SN150 is a solvent neutral grade typically used as Group I base stock. All three are high-saturate (>99.5% saturated hydrocarbons) and ultra-low sulfur (0.2–0.5 mg/kg range). API group classification is not stated on the COA — refer to the individual PDS for full property data.

Sanyang Base Oil SN150 is the preferred choice for grease manufacturing because of its higher viscosity (KV40 35.99 mm²/s) and viscosity index of 116. Base Oil 150N is also used in greases requiring slightly lower viscosity.

Choose TDAE (Treated Distillate Aromatic Extract) for tyre tread and high-aromatic rubber compounding, especially where DAE replacement is required under REACH. Choose Sanyang V1000 plasticizer for compounds that benefit from a naphthenic-paraffinic chemistry with lower aromatic carbon (CA 10.9% vs 19.3% for TDAE) and verified low PCA (2.6% per IP 346) and total PAH (2.61 mg/kg).

TDAE is the standard rubber process oil for passenger and commercial tyre tread compounds, supplied in Sanyang grades T100 through T1200. T100 (KV40 107.8 mm²/s) suits standard tread; T820 (KV40 818.6 mm²/s) is used for truck and OTR tyre compounds requiring higher viscosity.

Yes. TDAE is the standard REACH-compliant replacement for DAE (Distillate Aromatic Extract) in rubber compounding. The treatment process reduces polycyclic aromatic hydrocarbons (PAHs) to within the limits required for label-free rubber processing under EU REACH Annex XVII Entry 50.

Aromatic process oils (TDAE) have high aromatic carbon content (CA 19.3% in Sanyang T100/T820), giving strong solvency for high-diene rubbers like SBR and BR — preferred for tyre tread. Naphthenic-paraffinic oils (Sanyang V1000, CA 10.9%) offer lower aromatic content with good plasticizing performance, preferred for non-tread rubber goods, footwear, hoses, and applications sensitive to PAH content.

Both are label-free under EU PAH limits. Sanyang V1000 has documented total PAH of 2.61 mg/kg and benzo(a)pyrene of 0.34 mg/kg (SN/T 1877.3), with PCA at 2.6% per IP 346. TDAE is qualified as a low-PCA treated oil, but the Sanyang TDAE COA does not report a numeric IP 346 PCA value — request the latest batch COA for verified PAH/PCA figures.

TDAE T1200 is the heaviest grade (KV100 53.1 mm²/s, flash point 322°C, pour point 14°C). T820 (KV40 818.6, KV100 32.56) is the next heaviest. Heavier grades are used in truck/OTR tyre and high-viscosity rubber compounding where additional plasticization at temperature is required.

Not directly. V1000 is a naphthenic-paraffinic extender with lower aromatic carbon (10.9%) than TDAE (19.3%), so it does not provide equivalent solvency for SBR/BR tread compounds. V1000 is better suited to rubber compounds, footwear, hoses, belts, and technical rubber goods where naphthenic chemistry and low PCA/PAH are the priority.
