Logistics & Supply Standards

Celanese Zytel® 70G33HSL BK083 PA66 is packaged in standard 25kg moisture-proof sealed bags. As a solid engineering plastic pellet, it is not classified as a hazardous chemical and is free from special transportation control restrictions. Our global partner warehouses maintain regular safety stock long-term to steadily fulfill standard bulk orders. The average delivery lead time for domestic spot orders is 5 to 8 working days, while cross-border export orders require 10 to 15 working days, with specific delivery schedules subject to the agreed international commercial terms (Incoterms). The product complies with general cargo transportation regulations and can be co-loaded with other non-hazardous resins and plastic raw materials in consolidated containers, helping clients optimize consolidated procurement, unify logistics shipping, and reduce overall logistics costs.

Compliance & Quality Commitment

We can provide all purchasing clients with electronic and physical original copies of factory-certified Technical Data Sheets (TDS), Material Safety Data Sheets (MSDS), and Certificate of Analysis (COA) batch quality inspection reports. This material grade complies with EU REACH and RoHS hazardous substance control standards while meeting UL electrical safety specifications, fitting market access requirements for terminal products across most global countries and regions. All raw material batches undergo standardized production control and full-chain traceability systems, with each batch corresponding to independent production lot numbers, testing records, and warehouse release archives. This ensures full-process traceability from raw material production, quality inspection, and warehousing to delivery, safeguarding the performance consistency and quality stability of batch products.

Sustainability & ESG

Celanese Zytel® 70G33HSL BK083 is a thermoplastic polyamide material. Trimmings and defective products generated during production and processing can be recycled and reused through compliant crushing and regranulation processes, laying the foundation for a circular economy. The manufacturing process is optimized to strictly control volatile organic compound (VOC) emissions throughout, maintaining low VOC release levels during the molding and processing stage. Free from restricted hazardous substances, the material complies with global green supply chain auditing standards and sustainable production requirements. Its production base strictly adheres to industrial “three wastes” (wastewater, waste gas, and solid waste) treatment regulations, implements energy-saving and emission-reduction controls, and continuously aligns with the ESG supply chain audit systems of downstream brand clients.

Related FAQ (Frequently Asked Questions)

Q1: How should the drying process for this glass-fiber-reinforced PA66 grade be set prior to processing, and can the drying step be omitted?

A: PA66 materials are hygroscopic; 70G33HSL BK083 must undergo complete drying prior to processing and this step cannot be omitted. The standard recommended drying temperature is 90–100℃ for a duration of 4–6 hours. Strictly controlling raw material moisture content effectively prevents defects such as silver streaks, bubbles, and cracking during injection molding, ensuring stable mechanical performance and surface quality of the finished parts.

Q2: What is the core application difference between Zytel® 70G33HSL BK083 and standard non-heat-resistant glass-fiber-reinforced PA66?

A: This grade features a heat-resistant modified formulation with a heat distortion temperature reaching above 250℃, exhibiting smaller mechanical modulus degradation under high and low temperatures and more stable creep resistance. While standard glass-fiber-reinforced PA66 is only suitable for regular room-temperature working conditions, 70G33HSL BK083 can accommodate continuous high-temperature and high-load environments such as automotive engine bays and high-temperature electrical equipment over the long term, making it ideal for scenarios demanding higher long-term dimensional stability and structural strength.

Q3: What electrical component scenarios does this material’s electrical performance suit, and does it meet high-voltage operating requirements?

A: With a comparative tracking index (CTI) reaching 600V and excellent volume resistivity values under normal states, this product exhibits favorable electrical insulation performance and can satisfy the operational requirements of regular low-voltage electrical and electronic components as well as insulating structural parts. Since its flammability rating is UL94 HB, it is not suitable for special electrical applications requiring high voltage and high flame retardancy; specialized flame-retardant modified PA66 grades should be selected for high-voltage and high-flame-retardant scenarios.
