자주 묻는 질문

Common questions about sourcing, compliance and documentation across our product range.

C5/C9 석유수지와 C9 석유수지의 차이점은 무엇인가요??+

C5/C9 copolymer petroleum resins combine aliphatic and aromatic feedstocks and are selected for a balance of colour, compatibility, adhesion and softening point. C9 aromatic petroleum resins generally offer stronger aromatic compatibility and may have different colour and thermal characteristics. Performance varies significantly by grade, hydrogenation level and application, so supplier data and formulation trials should be compared.

SUNCHEM은 어떤 PA 등급을 공급합니까??+

SUNCHEM can source selected PA6 and PA66 grades for injection moulding, extrusion, fibre and other applications. Available viscosity, additive package, reinforcement, colour and packaging depend on the manufacturer and grade. Buyers should provide the processing method and target properties before grade selection.

귀사의 식품 첨가물은 EU 및 미국 시장 사용에 적합한가요??+

Suitability must be confirmed for the exact ingredient, grade, manufacturer, intended use and destination market. SUNCHEM can provide available specifications and supporting documents and can check whether a product is supplied against relevant EU, 미국 FDA, FEMA, FCC or other requirements. Final regulatory approval and permitted use level remain the responsibility of the finished-product manufacturer and importer.

What is Zinc Pyrithione used for?+

Zinc pyrithione is an antimicrobial ingredient used in certain industrial and formulated-product applications. Permitted uses vary significantly by country and product category, and some former cosmetic uses are restricted in certain markets. Buyers must confirm the intended application, local regulatory status and required grade before sourcing.

How long does delivery take for paint and pigment chemicals from China?+

Lead time depends on production availability, quality approval, 포장, dangerous-goods booking, destination and shipping method. SUNCHEM confirms an estimated production and transit schedule for each quotation rather than applying one standard delivery time to all products.

SUNCHEM은 중국에서 어떤 유기용매를 공급하나요??+

SUNCHEM supplies selected solvents and fine-chemical intermediates, including products used in coatings, 접착제, 청소, extraction and chemical synthesis. Because the current category includes both true solvents and specialty intermediates, buyers should search by product name or CAS number and confirm specification, hazard class and application requirements.

Are paint and pigment chemicals REACH or RoHS compliant?+

Compliance must be checked for the exact substance, manufacturer, tonnage band, use and destination market. SUNCHEM can request available REACH, RoHS or other regulatory documentation from the selected source, but no category-wide compliance statement should be assumed.

COA를 제공할 수 있나요?, SDS and TDS for paint and pigment chemicals?+

COA and SDS are generally available for suitable products, while TDS and additional analytical documents depend on the exact grade and manufacturer. Documentation should be confirmed before order placement, especially where impurity, colour strength, regulatory or application-specific data are critical.

수처리에 HEDP는 무엇을 위해 사용됩니까??+

HEDP is a phosphonate used as a scale and corrosion inhibitor in industrial water systems. It can help control deposits involving calcium salts and metal ions and is used in applications such as cooling-water treatment, boilers and certain cleaning formulations. Performance depends on water chemistry, pH, temperature and the complete treatment program.

Are your hair dye intermediates compliant with EU cosmetics requirements?+

Compliance depends on the exact substance, 불순물 프로필, permitted use, concentration and current destination-market rules. SUNCHEM can provide available specifications and analytical information for evaluation, but the formulator and responsible person must confirm that the finished cosmetic product meets applicable regulations.

SUNCHEM이 공급하는 수처리 약품은 무엇입니까??+

SUNCHEM can supply selected scale and corrosion inhibitors, 살생물제, 소독제, coagulants and other water-treatment chemicals, including phosphonates, isocyanurates and selected brominated or non-oxidizing biocides. Availability and permitted use depend on the exact product, application and destination-market regulations.

Are your amino acids food grade or pharmaceutical grade?+

Selected amino acids may be available in food, feed, nutraceutical or pharmaceutical grades. The applicable monograph, assay, microbiological limits, endotoxin requirements and supporting certificates depend on the exact product and manufacturer. Buyers should specify the intended use and required FCC, USP, EP, JP or other standard before quotation.

SUNCHEM은 어떤 종류의 페인트 및 안료 화학 물질을 공급합니까??+

SUNCHEM supplies selected dye and pigment intermediates, aromatic amines, 아미노페놀, resorcinol derivatives and other specialty chemicals used in coatings, 잉크, textile dyes and colourant manufacturing. Buyers should provide the exact product or CAS number because end-use suitability and regulatory requirements vary widely.

제약 중간체와 함께 제공되는 문서는 무엇입니까??+

Available documentation may include a specification, recent COA, SDS, TDS and selected analytical or impurity information for the exact product and manufacturer. Additional items such as residual-solvent data, elemental-impurity information, REACH status or regulatory support must be confirmed case by case according to the intermediate, manufacturing site and destination market.

어떤 카바페넴 항생제를 사용할 수 있나요??+

Carbapenem API availability must be confirmed individually because manufacturing authorization, sterile-processing requirements, patent or market restrictions and regulatory documentation vary by product and destination. Please provide the exact API, grade, quantity and target market for a source review.

Are your APIs sourced from GMP-certified manufacturers?+

GMP status must be verified for the exact API, manufacturing site and destination market. For suitable projects, SUNCHEM can screen manufacturers and provide available GMP certificates, regulatory documents and audit-related information subject to confidentiality and supplier approval. Buyers should complete their own regulatory and quality qualification before commercial use.

What antiretroviral APIs can SUNCHEM source?+

Availability of antiretroviral APIs depends on the product, manufacturing authorization, destination market, regulatory status and current supply conditions. Buyers should provide the INN, required pharmacopoeial standard, 수량, market and dossier requirements so that SUNCHEM can confirm whether an appropriate source is available.
