Zhenghang is leading manufacturer for Postforming Compact. Postforming Compact is made of the decorative paper immersing by the melamine-formaldehyde resin and adding some black or brown kraft papers immersing by the phenolic resin, and then using the plate steel to press under the
high temperature (150°C) and
high pressure (1430psi). The thickness of the compact is from 1.6mm to 25mm.

Limitations
Storage
Compact sheets should be stored horizontally, with a caul board or other protective sheet placed on top to protect the material from possible damage. The material should be protected from moisture, and should never be stored in contact with the floor or an outside wall. Optimum conditions for storage are approximately 75°F (24°C), and 45% to 55% relative humidity.
Compact sheets moves with changes in humidity, but less than standard high pressure laminate (HPL) sheet. Allow Compact sheets to acclimate for at least 48 hours to ambient conditions prior to fabrication. Optimum conditions are approximately 75°F (24°C), and at a relative humidity of 45% to 55%. Provisions should be made for the circulation of air around the material.
If required, thinner variations of Compact sheets may be bonded to 45# density, industrial-grade particle board (ANSI A208.1-1999), medium density fiberboard (MDF), or hardwood-faced luan plywood. Softwood fir and other plywood have different dimensional stability and are not recommended as substrates. The substrates should be sanded smooth, clean, free of oil or grease, and uniform in thickness.
Adhesive
Assembly
Material, equipment, and workmanship should conform to the industry standard practices, conditions, procedures, and recommendations as specified by ANSI/NEMA LD3-2005. Compact sheets can be sawed, drilled, routed, and fabricated similarly to standard HPL. Carbide-tipped cutting tools are recommended. All inside corners of cutouts must be radiused as large as possible, 1/8" (3.18mm) minimum, to avoid stress cracking. The edges and corners should be routed, sanded, or filed smooth and free of chips or nicks.
