Detailed Product Descriptions and Features
1.Hydroxypropyl Methyl Cellulose (HPMC)
HPMC is a non-ionic cellulose ether widely used as a thickener, emulsifier, film former, and stabilizer in pharmaceuticals, construction, and food industries. It is valued for its water solubility, excellent film-forming ability, and chemical inertness. In construction, it improves workability and water retention of cement and plaster. In pharmaceuticals, it acts as a binder and controlled-release agent in tablets. Its versatility and safety profile make it a key additive in diverse formulations.
2. Acetylsalicylic Acid (Aspirin)
A well-known pharmaceutical compound, acetylsalicylic acid is widely used as an analgesic, anti-inflammatory, and antipyretic agent. TSR Chem supplies high-purity acetylsalicylic acid suitable for pharmaceutical manufacturing. Its consistent quality ensures reliable efficacy in drug formulations. This product is critical in healthcare for pain relief and cardiovascular protection due to its blood-thinning properties.

3. Methyl Salicylate
Methyl salicylate is an organic ester commonly used in flavorings, fragrances, and topical analgesics. It provides a characteristic wintergreen scent and is used in ointments and liniments to relieve muscle and joint pain. Its high purity and consistent quality from TSR Chem make it suitable for pharmaceutical and cosmetic applications.
4. Sodium Salicylate
Sodium salicylate is a salt of salicylic acid with applications in medicine as an anti-inflammatory agent and in industrial processes such as corrosion inhibition. It is also used as an intermediate in the synthesis of other pharmaceuticals. TSR Chem's sodium salicylate is characterized by high purity and stability, ensuring effective performance in various formulations.
5. Xanthan Gum
Xanthan gum is a polysaccharide used as a food additive and rheology modifier. It acts as a thickener, stabilizer, and emulsifier in food products, cosmetics, and pharmaceuticals. Known for its excellent viscosity and stability over a wide pH range and temperature, xanthan gum enhances texture and shelf life. TSR Chem provides xanthan gum with consistent quality suitable for food-grade and industrial applications.

6. Toluene Diisocyanate (TDI)
TDI is a critical raw material in the polyurethane industry. TSR Chem offers industrial-grade TDI with 99% purity, mainly used in producing polyurethane foams, coatings, elastomers, adhesives, and sealants. TDI's reactive isocyanate groups enable it to form strong polymer networks, imparting flexibility, durability, and chemical resistance to polyurethane products. TSR Chem's TDI is supplied in liquid form, packaged in 250 kg drums, with a monthly supply capacity of 3000 tons, ensuring reliable availability for large-scale industrial use.
Key Features of TSR Chem's TDI:
- High purity (99%) ensuring efficient polymerization
- Industry-grade quality suitable for diverse polyurethane applications
- Stable liquid form with controlled melting and boiling points for safe handling
- Supplied in standardized packaging for ease of transport and storage
- Widely used in flexible and rigid foams, coatings, adhesives, and fibers
7. Polypropylene Glycol (PPG) and Related Polyols
Polypropylene glycol and its derivatives are versatile polyether polyols used as intermediates in polyurethane production. They contribute to the flexibility, toughness, and chemical resistance of polyurethane elastomers and foams. TSR Chem's polypropylene glycol products are characterized by controlled molecular weights and purity, enabling precise formulation of polyurethane systems tailored for automotive, furniture, and insulation applications.
