1. ABS Resin Production：Most important application, as chain transfer agent for ABS polymerization to control molecular weight and molecular weight distribution of polymer.
2. Synthetic Rubber：Used in styrene-butadiene rubber, nitrile rubber polymerization process for molecular weight adjustment.
3. Acrylic & Styrene Polymer：Chain regulator for acrylic resin, polystyrene, emulsion polymerization products.
4. Chemical Intermediate：Raw material for synthesis of rubber vulcanizing agent, antioxidant, sulfur-containing fine chemicals.
5. Oil-field chemical auxiliary：Can be applied for partial oil-field chemical formula as additive.
1. The quality is benchmarked against imported major manufacturers, with stable isomer composition.
We produce independently, strictly control the distribution of light and heavy components, and the sulfur content is stable. The molecular weight adjustment effect of each batch is highly consistent.
2. Abundant stock + flexible production scheduling, controllable delivery time
We have regular industrial-grade stocks, eliminating the need for long waiting for import shipping schedules and avoiding risks of overseas supply disruptions, price hikes, and exchange rate fluctuations. The high-purity refined version can be scheduled according to orders, supporting stable long-term lock-price agreements.
3. Customizable indicators, supporting refined low-odor versions
Regular ≥ 98.5%; customizable refined versions with low light components and low coloration, effectively reducing residual odors in the finished products, suitable for customers requiring high odor standards such as latex and modified resins; each batch comes with a COA, with transparent indicators.
4. Full compliance throughout the hazardous chemicals shipment process
We have corresponding qualifications for hazardous chemicals production and operation, with complete packaging, SDS, and MSDS, reducing customer customs declaration and compliance troubles.
5. Technical support for application integration
We provide technical support for polymerization applications, assisting customers in referring to the addition range, feeding method, storage protection plans; providing samples for formula gradient testing, and connecting with on-site process issues.
6. Stable supply chain and after-sales service
Our own production line, no resale of goods; liquid filling is standardized, leak-proof; in case of abnormal indicators, we will cooperate in rapid rechecking and after-sales handling, and long-term customers can negotiate price and delivery plans.
Standard packaging ：170kg/drum.
1. Temperature: 2 – 30℃, in a cool storage room, avoid direct sunlight and heat sources and open flames; for short-term storage, it can be kept at low temperature, but must not be exposed to high temperatures and direct sunlight.
2. Container: Original sealed coated metal drums; after opening, the seal must be re-tightened, the drum should stand upright to prevent leakage; for long-term storage, inert gas protection is recommended to reduce oxidation by contact with air.
3. Environment: Dry, well-ventilated storage room; the storage location should be managed with locks.
4. Isolation Prohibitions: Strictly prohibited to be mixed with strong oxidants, strong acids, and strong bases; when exposed to acid, toxic mercaptan fumes will be released; keep away from food and drinking water.
Q: Sample policy?
A: Samples can be provided. The shipping cost is borne by the customer. For samples of 1L or more, the charge is based on the unit price of the bulk order. After placing the bulk order, the sample fee can be refunded. The samples will be dispatched within 1-2 working days, along with COA and SDS.
Q: What is the purity of the product?
A: The industrial mainstream specification is ≥ 98%, it is a mixture of isomers of tertiary dodecyl mercaptan; a COA analysis certificate is provided.
Q: MOQ, delivery time?
A: MOQ: 200kg (minimum order quantity is a full barrel); normal delivery time is 7-10 working days; custom packaging requires separate confirmation.
Q: What documents are provided?
A: Provide complete MSDS/SDS/COA, related bills of lading.
Q: What are the storage precautions? Will it freeze?
A: Storage temperature is controlled at 2-30℃, protected from light, ventilated, and sealed; the melting point is -7.5℃, and it will not solidify in a regular warehouse; in extremely low temperatures in winter, it will become thick and viscous, and after warming up, it will return to a liquid state, without affecting the quality. It is prohibited to store together with oxidants and strong acids, and the opened container should be used up as soon as possible to avoid long-term exposure to air for oxidation and discoloration.
Q: The smell is very strong, is it normal?
A: Mercaptans have an inherently strong and unpleasant smell, which is a characteristic of the product; the refined version will have a relatively lower smell. The operating environment must maintain strong ventilation, wear protective gloves and goggles to avoid inhaling vapors.
