PU core material is a polyurethane (PU) material Polyurethane is a polymer compound, formed by polyols and polyisocyanates through polycondensation reaction, with excellent mechanical properties and high plasticity.

Features of PU core materials include:

Low thermal conductivity: Polyurethane has good thermal insulation properties and is an excellent thermal insulation material.
Good fire resistance: The polyurethane core material has reached B1 combustion performance and has good fire performance.
Non-toxic and tasteless: safe to use, non-toxic and tasteless, environmentally friendly and healthy.
Chemical resistance: It has good chemical resistance and high stability.
Easy installation: The polyurethane core material is easy to install, the construction period is short, and the comprehensive benefits are good.
PU core materials are widely used in various fields, including:

Construction: Wall and roof envelope systems for industrial plants, logistics and warehousing, and integrated

XPS core is a kind of insulation material with polystyrene resin as the main component XPS core, the full name of Extruded Polystyrene, that is, extruded polystyrene, is a closed-cell foam board made by a special process. It is made of polystyrene resin as the main raw material, and then added to other chemical materials, which has excellent thermal insulation performance, high strength and durability.

The XPS core manufacturing process involves heating and mixing polystyrene resin and other raw and auxiliary materials, and then extrusion molding into rigid foam sheets. This material has a perfect closed-cell honeycomb structure, which makes the XPS board have extremely low water absorption, pressure resistance, aging resistance and other characteristics. Due to its many pores on the surface, XPS cores perform well in thermal insulation, thermal insulation and sound insulation, and almost do not absorb water and have strong resistance to aging, so they are very suitable for exterior w

Foamed PET core is a material mainly made of polyethylene terephthalate (Polyethylene terephthalate, referred to as PET). This material is commonly known as polyester resin, which has good heat resistance, mechanical strength and environmental performance.

Foamed PET core material is widely used in many fields. Due to its good heat resistance, mechanical strength and environmental performance, foamed PET core material is used in building insulation materials, sandwich structure material core materials, sports equipment, wind turbine blades, ships, aerospace and other fields. For example, the CYGNUS A10 drone fuselage is mainly built with a high-performance composite material with a Divinycell H foam core (i.e. PET foam core) as the sandwich core.

PP honeycomb core is a new type of structural material made from PP resin based on the biomimetic principle of honeycomb.
Product feature: high strength, lightweight, eco-friendly, flexibility in use, it can be compouned with different materials.
Application: honeycomb core materials have significantly replaced traditional materials, it is widely used in vehicle lightweighing, air purifiers, aerospace, yachts, mobile building.
