ORYZA SIL 650

A high-performance aerogel blanket built to withstand extreme temperatures across energy applications. Exceptional hydrophobicity and breathability give superior protection against corrosion under insulation, with excellent passive fire protection.

Why SIL 650

01

Best-in-class CUI defence

Hydrophobicity, breathability, a thin profile, chemical resistance and durability keep water and corrosive substances away from the metal surface.

02

Fire performance, Grade A1

Euroclass A1 non-combustible, with excellent passive fire protection properties.

03

Safer to install

Low dust and low density make it easy to handle, and there is no crystalline silica content in residual dust, so it is safe for workers on contact.

04

Durable and long-lasting

Holds its shape and performance at sustained high temperature, with fewer replacements and less maintenance.

05

Streamlined logistics

Tailored to fit pipes, vessels, valves and flanges, significantly reducing material handling and inventory costs.

06

Lower construction costs

A lightweight profile allows smaller pipe racks and foundations, with substantial savings on steel, concrete and labour.
