Perlite’s cellular structure and successive air compartments prevent sound waves from propagating, making it an ideal filler for sound-blocking and sound-absorbing applications. A combination of an interconnected pore structure and cavity resonance sound absorption structure results in a higher performance, sound absorption/blocking material that is used as a filler.

Expanded Perlite Insulation Board
The perlite perforated core plate is made of natural perlite ore, which is formed by a hollow honeycomb-shaped granular spherical body which is instantaneously expanded at a high temperature of 1350 ° C or higher. Therefore, the fireproof door core plate is a ideal product for environmental protection.
Feature:
Non-toxic, non-combustibility, corrosion resistance, sound and thermal insulation.
Application:
It is a new fireproof door core filling material and sort of natural and environmental product, and it can reach fireproof grade A1 according to National Fireproof New Standard combing application with steel or wooden door.
Construction Industry: Big users of perlite research suggests that more than 50 percent of expanded perlite worldwide is used by the construction industry. Perlite plays an important role in a wide variety of construction-related uses including: as an aggregate in lightweight insulating concrete and plaster; as a loose fill insulation material for concrete masonry blocks, cavity walls, in residential homes; and in a variety of specialty applications including fireproofing sprays, chimney fills, interstitial floors, acoustical sprays, etc.
Lightweight Perlite Insulating board offers several important benefits for architects, engineers, and building owners:
• Superior thermal performance with high insulating values
• Non-combustible with superior fire ratings
• Lightweight and durable
• Smooth monolithic slope-to-drain surface
• Roofing material can be nailed or glued
• Meets UL and FM wind uplift criteria
• An innovative hybrid technology improves cellular concrete
• Realize savings in time, labor, and materials
