Technical Data

WELLBOND Aluminum Composite Panel is (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 firm-able material with an excellent strength to weight ratio.

PRODUCT COMPOSITION

WELLBOND ACP is basically composed of the following materials:

1. PROTECTIVE FILM

The decorative surface is being protected by an 80-micron 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.

2. POLY VINYLIDENE DEFLOWERED (PVDF) COATING

A high non-reactive and pure fluoropotymer
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.

3. 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.

4. 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 Alloy3003 H18 / 3105 H18
ThicknessUp to 0.50 mm

5. BONDING FILM

CORE MATERIAL

LOW DENSITY POLYETHYLENE CORE (LDPE) WELLBONO 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 sheer or opaque variations, it is quite flexible and tough yet unbreakable.
(1) The film properties have been measured on Hp0722n (50p film, 2.5’1 blow-up ratio)

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°C at extrusion.

FIRE RETARDENT ALUMINUM CPOMPOSITE PANEL "A2 ORGANIC CORE"

is a non-combustible mineral and organic core, with no halogen, no smoke and fume. It is used for (ACP A2) consisting of two aluminum cover sheets and a noncombustible core consists of 95 % mineral filled and. mineral used is brucite (natural magnesium Hydroxide) OR ATH: AL(OH)3.

FIRE RETARDENT ALUMINUM COMPOSITAE PANEL "A2 ALUMNIUM CORE"

the WELLBOND is a newly developed composite panels that 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.
