Hostaform S 9364 LPB – Low Permeation Impact Modified POM-C for Blow Molding

描述

Hostaform S 9364 LPB is a low permeation, highly impact modified acetal copolymer (POM-C) grade, genuinely manufactured by Celanese and imported as original product. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Celanese technical documentation.

This unfilled acetal copolymer is a low-permeation and toughened (LPT) grade specifically designed for blow molding applications in fuel systems that use advanced fuels. Hostaform S 9364 LPB provides a significant improvement in impact strength and flexibility over standard impact modified grades.

The “LPB” designation stands for Low Permeation Blow molding – indicating this grade is specially formulated for blow molding of fuel tanks and containers requiring low fuel permeation. Celanese specifically designed S 9364 LPB for blow molding to perform in fuel systems that use ‘advanced fuels’.

Hostaform S 9364 LPB is a very hard and rigid, heavy-metal free POM copolymer grade that exhibits outstanding chemical resistance (solvents, fuels & strong alkalis), hydrolysis resistance, fatigue resistance, creep resistance, moisture resistance, and stress cracking resistance. With regular stock availability, we support both trial orders and large‑volume bulk shipments for automotive, small off-road engine, and industrial applications.

Processing Guidelines (Blow Molding & Injection Molding)

Recommended processing parameters for Hostaform S 9364 LPB:

Critical Processing Warnings for Hostaform S 9364 LPB:

• Blow Molding Processing: With extremely low MVR of 0.6 cm³/10min – the lowest in the S 9364 series – Hostaform S 9364 LPB provides the high melt strength essential for parison stability during extrusion blow molding. Fine‑tune extrusion parameters (die geometry, melt temperature, blow pressure) for optimal component results.

• Drying: Drying is not normally required. However, should there be surface moisture (condensate) on the molding compound as a result of incorrect storage, drying is required. Recommended drying: 80-100°C for 3-4 hours.

• Low Permeation Property: To maintain low permeation characteristics essential for EPA/CARB compliance, avoid contamination and ensure proper processing conditions.

• Thermal Degradation Risk: POM‑based material can decompose under excessive heat and release formaldehyde vapors. Guarantee sufficient ventilation; avoid overly long barrel residence times. Max. melt temperature 210°C.

• Material Purity Requirement: Strictly prevent cross‑contamination with other polymer grades. Contamination will degrade the low permeation and impact properties.

• Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty grade. Reprocessing may compromise the low permeation characteristics, impact properties, and EPA/CARB compliance. If regrind usage is mandatory, keep percentage below 10% and complete pre‑validation testing first.

• Storage Guidance: Store pellets in cool, dry conditions; keep sealed in original factory packaging whenever possible.
