The closed-cell hydrophobic modification technology solves the water absorption defect of ordinary perlite. It reaches Class A fire resistance with low thermal conductivity, and is suitable for exterior wall insulation mortar, heating pipeline insulation, low-temperature equipment filling and roof backfill projects.
Adopting graded grinding and deep purification technology, this filter aid has stable chemical properties without harmful substance precipitation. It features fast filtration speed and high filtrate clarity, fully meeting food contact safety standards, and is suitable for purification of edible oil, fruit juice, fermentation liquid and industrial chemical liquid.
This expanded perlite has a neutral pH value and sterile porous honeycomb structure. It balances water permeability, air circulation and fertilizer storage, effectively preventing growing medium hardening and seedling root rot. It is widely used in greenhouse soilless cultivation for vegetables and flowers, and customized particle sizes and neutral OEM packaging are supported.
