描述
Hostaform RF2464WR BLK2 is a weather-resistant, impact modified acetal copolymer (POM-C) specially designed for rotational molding (rotomolding) applications. As an authorized distributor and trader, we supply genuine material with full traceability and direct access to official Celanese technical documentation.
This rotomolding grade is formulated to withstand the long hot cycle times unique to the rotomolding process. Hostaform RF2464WR BLK2 is an impact-modified POM with enhanced weather resistance (WR) , available in precolored black (BLK2) . The melt flow characteristics (MVR ≈ 2.5 cm³/10min) and thermal stability are specifically optimized for the rotomolding process, enabling uniform coating of the mold interior to form hollow parts with consistent wall thickness and minimal internal stress.
Hostaform RF2464WR BLK2 is a single-layer solution for fuel tanks that does not require fluorination or other secondary treatments. It delivers an unprecedented balance of impact and durability performance along with low fuel permeation that customers need to meet U.S. EPA regulations. The “WR” designation indicates enhanced weather resistance for demanding outdoor applications, while “BLK2” specifies the precolored black formulation. With regular stock availability, we support both trial orders and bulk shipments for small off-road engine and marine fuel tanks, hydraulic reservoirs, and industrial bulk containers.

Critical Processing Warnings for Hostaform RF2464WR BLK2:
Processing Method: Primarily recommended for rotational molding (rotomolding). Can also be used for injection molding or extrusion, but processing parameters must be adjusted.
Temperature Limits: Hostaform RF2464WR BLK2 should not be heated above standard rotomolding temperature limits. Excessively high temperatures can cause resin degradation and release of formaldehyde.
Thermal Degradation: Like all POM materials, excessive heat or prolonged residence time can cause degradation, which may release formaldehyde, a colorless and irritating gas.
Storage: Hostaform POM should be stored in its original container on pallets in a dry place. Open containers should be carefully resealed before returning to storage.
Material Purity: Strictly prevent cross‑contamination with other polymer grades. Contamination will compromise the low permeation, impact, and weather-resistant properties.
Regrind / Recycled Material Notice: We do not recommend adding regrind for this specialty rotomolding grade. Re-processing may compromise the low permeation, impact, and weather-resistant properties. If regrind usage is mandatory, keep percentage below 10% and complete pre‑validation testing first.
