About Sinty Sci-tech Co., Ltd. - Fabric and Raw Material Supplier in China

Sinty Sci-tech Co., Ltd. is based in China and currently lists six active products across several industrial categories. The catalogue includes a PP1500 polypropylene grade for meltblown fabric production, a 75 % ethanol solution formulated for hand‑sanitising applications, and a Kunlun fully refined paraffin wax intended for candle manufacturing. Additional offerings are a 100 % organic soy wax (HS 1521.90) derived from Glycine max, a diethyl carbonate (DEC) electrolyte for lithium‑ion batteries (HS 2917.19, electronic grade 99.9 % purity), and a polycarboxylate ether (PCE) superplasticizer for concrete (HS 3824.40). The product list spans polymer raw material, chemical disinfectant, waxes for candle making, battery electrolyte, and construction admixtures, each identified by its respective HS‑code family. The six items reflect a focus on specialty chemicals and polymer‑based inputs rather than finished consumer goods. All entries are presented with material specifications such as polymer type, ethanol concentration, or purity level, which are typical data points required for bulk sourcing. No additional product lines or services are mentioned beyond the items enumerated in the catalogue.

Product Range and Specialties of Sinty Sci-tech Co., Ltd.

The polypropylene offering, PP1500, is positioned for meltblown fabric lines used in filtration media. In the meltblown sector, grades are often selected by melt flow index (MFI) ranging from 5 to 30 g/10 min and by isotacticity that influences fiber strength. The 75 % alcohol disinfectant aligns with WHO-recommended hand‑rub formulations, where ethanol purity is usually above 96 % before dilution to 75 % v/v, and the solution must meet limits on methanol and impurity residues. The wax portfolio includes a fully refined paraffin wax and a 100 % organic soy wax (HS 1521.90). Paraffin wax for candles typically exhibits a melting point between 52 °C and 60 °C, an iodine value below 10, and a flash point above 200 °C, while soy wax is valued for a lower melting range (45‑55 °C) and a higher cloud point, often tested to ASTM D6866 for bio‑based content. The diethyl carbonate electrolyte (HS 2917.19) is supplied at electronic grade 99.9 % purity, matching the high‑purity specifications (≤10 ppm water, ≤5 ppm metal ions) required for lithium‑ion cell production. Finally, the HPEG/TPEG‑based PCE superplasticizer (HS 3824.40) conforms to concrete admixture standards such as ASTM C494, with typical dosage rates of 0.2‑0.5 % by cement weight and water‑reduction efficiencies of 15‑30 %.

Trade and Export Information - Sinty Sci-tech Co., Ltd.

China is a major exporter of polymer intermediates, chemical solvents, waxes, and construction additives, with Europe, North America, and Southeast Asia representing the largest import markets for these categories. The HS‑code families present - 1521 (wax), 2917 (organic chemicals), and 3824 (chemical products for industry) - are routinely inspected under customs regimes that reference REACH compliance for the EU and TSCA for the United States. Buyers often request certificates of analysis, REACH registration dossiers, and MSDS documents before freight release. Typical logistics involve bulk shipments in 20‑ft or 40‑ft containers for waxes and superplasticizers, while the electrolyte is commonly packed in intermediate bulk containers (IBCs) or drums to meet UN 38.3 safety requirements for hazardous liquids. Incoterms such as FOB Shanghai or CIF Los Angeles are standard for these goods. Export licensing in China for chemicals like diethyl carbonate may involve the Ministry of Commerce, and compliance with the International Maritime Dangerous Goods (IMDG) code is required for the electrolyte and high‑proof ethanol solution.

Sourcing from Sinty Sci-tech Co., Ltd. - Buyer Guidance

When sourcing the polypropylene meltblown grade, request the material data sheet specifying melt flow index, density, and tensile strength, as well as a recent certificate of analysis confirming isotacticity and melt temperature range. For the 75 % ethanol disinfectant, verify the batch’s purity, methanol content, and pH by requesting an analytical report and the relevant MSDS. The soy wax should be accompanied by a bio‑content certificate (e.g., ASTM D6866) and a melting‑point test report; the paraffin wax requires a flash‑point test and iodine value. The diethyl carbonate electrolyte must be supplied with a purity certificate, water content analysis (Karl Fischer), and compliance documentation for UN 38.3 and IEC 62133 if the buyer intends to use it in battery cells. For the PCE superplasticizer, obtain a performance test report that includes water‑reduction percentage, dosage range, and viscosity measurements per ASTM C494. Across all products, confirm that the supplier can provide REACH registration numbers (for EU imports) or equivalent regulatory filings, and negotiate packaging details such as IBC drums for liquids or sealed polyethylene bags for waxes, with clear labeling of HS codes for customs clearance.

What HS codes are associated with the wax products listed by Sinty Sci-tech?

The 100 % organic soy wax is classified under HS 1521.90, which covers other waxes not elsewhere specified. The paraffin wax for candle making falls under the broader HS 1521 chapter for waxes and waste wax.

Which certifications should a buyer request for the diethyl carbonate electrolyte?

Buyers should request a Certificate of Analysis showing 99.9 % purity, a REACH registration excerpt, and compliance documents for UN 38.3 and IEC 62133, which are standard for lithium‑ion battery electrolytes.

What typical purity or concentration specifications apply to the 75 % alcohol disinfectant?

The ethanol solution should be 75 % v/v with ethanol purity above 96 % before dilution, methanol content below 0.5 % and a pH between 6.5 and 7.5, matching WHO hand‑rub guidelines.

How is the PP1500 polypropylene grade typically evaluated for meltblown applications?

Evaluation focuses on melt flow index (MFI) in the range of 5‑30 g/10 min, density around 0.90‑0.92 g/cm³, and isotacticity that ensures fiber strength and uniformity in meltblown processes.

What are common packaging formats for the PCE superplasticizer?

The superplasticizer is usually supplied in sealed polyethylene drums or 20‑ft containers with moisture‑proof liners, and each package is labeled with HS 3824.40 and a safety data sheet.

Which markets typically import the polymer and chemical products exported from China?

Europe, North America, and Southeast Asian countries are the primary import destinations for Chinese polypropylene, ethanol disinfectants, waxes, battery electrolytes, and concrete admixtures.

What documentation is required for customs clearance of the listed chemicals?

Customs generally require a commercial invoice, packing list, the relevant HS code, a Material Safety Data Sheet (MSDS), and proof of REACH or TSCA compliance depending on the destination market.

What are the usual minimum order quantities for the soy wax and DEC electrolyte?

Buyers often encounter a minimum order of 20 metric tonnes for bulk soy wax shipments and 500 kg to 1 tonne for diethyl carbonate electrolyte, reflecting standard lot sizes for chemical bulk trade.
