WELLBOND Aluminum Composite Panels (ACP) is a high-performance product consisting of two sheets of Aluminum bonded permanently to each side of an extruded core material made of low-density polyethylene core or fire retardant core. It is a simple concept resulting in an extraordinarily flat and highly formable material with an excellent strength to weight ratio.
2. Product Composition
WELLBOND ACP is basically composed of the following materials:
- POLY VINYLIDENE DIFLUORIDE (PVDF) COATING – a high non-reactive and pure fluoropolymer coating used in applications requiring the highest purity, strength, resistance to solvents, acids, bases and heat, and low smoke generation during a fire event. PVDF is not susceptible to attack by UV light, so the resin does not break down on exposure to sunlight which gives a very high resistance to fading and chalking and a very good long-term maintenance of gloss and color.
- ALUMINUM SHEETS – two sheets of aluminum bonded to each side of a polyethylene core. They have excellent tensile strength, yield strength and elongation rate and were rated high resistance to corrosion.
|Type of Alloy||3003 H18 / 3105 H18|
|Thickness||Up to 0.50 mm|
- CORE MATERIAL:
LOW DENSITY POLYETHYLENE CORE (LDPE) – WELLBOND LDPE is a thermoplastic made from petroleum. It is non-reactive at room temperatures, except by strong oxidizing agents. It can withstand temperatures of 800C continuously and 950C for a short time. Made in translucent or opaque variations, it is quite flexible and tough but breakable.
FIRE RETARDANT CORE (KT-A/B-FRPE): is a non-combustible mineral filled core, with no halogen, low smoke and fume. It is used for FRACP consisting of two aluminum cover sheets and a noncombustible mineral filled core. The mineral used is brucite (natural magnesium Hydroxide) OR ATH: AL(OH)3. The compound allows melt temperatures of 130-280℃ at extrusion.
FIRE RETARDENT ALUMINUM CPOMPOSITE PANEL “A2 ALUMNIUM CORE”
The WELLBOND is a newly developed composite panels which can be used in place of conventional PE, and FR core panels. This is also applicable in place of Honey comb and solid cladding sheets.
- POLYESTER COATING – a seven micrometer (7um) polyester-based coating in back aluminum sheet which serve as aid in protecting WELLBOND ACP from possible corrosion problems which may come from the corrosive substance from backside.
The decorative surface is being protected by an 80-micrometer thick self-adhesive protective film to protect it from scratch and any possible damages during processing, storage and installation. It is composed by two colors, white with WELLBOND logo in outer side to reflect ultra-violation and black in inner side to prevent ultra-violation.
