HITEX CORE PM is an engineered, cost-effective solution for closed mould composite processes, distinguished as a pressure-stable polyester non-woven fabric that uniquely functions as both a core material and an infusion medium. It is fully compatible with all conventional resin systems, including Unsaturated Polyester Resin, Vinyl ester, Phenolic, and Epoxy,and is thus perfectly suited for sophisticated closed mould techniques such as Infusion, RTM Light, and RTM Heavy.
FEATURE
*The product has a diversion groove as a diversion medium; No need to use additional diversion materials
*Better compressive performance
*As a choice for low-cost core materials
*Reduce product weight
*Increase product rigidity
*Can make the appearance of the product more beautiful
*Excellent conformal performance
*Excellent impact resistance
*The thickness of the product can be controlled as needed
*Max thickness 10mm, hexagonal core with non-absorbing resin, low compression rate (10%@-0.8bar)
*Flow channel 0.5mm, between adjacent hexagons to accelerate resin flow
APPLICATION
*Marine: hulls, decks and structures of boats and yachts
*Transportation: parts and panels of cars, trailers, trucks and RV’s
*Mass transit: interior and exterior of trains, light rail and buses
*Leisure: kayaks, surfboards, pools and tubs ,Swimming Pool and bathroom
*Industrial: Furniture , cladding panels, fans, containers and tanks
*Wind energy:nacelle covers and spinners
