Goodfellow’s new high-temperature insulation material

by Goodfellow Cambridge Ltd

Leading research materials supplier, Goodfellow, recently announced the launch of a new high-temperature insulation material, High Density Calcium Silicate. Available to customers now, the new material can be described as an alternative to the discontinued Duratec® 750.

With over 6,000 customers supported by a worldwide network of offices, agents and distributors, Goodfellow is a leading global supplier of metals, alloys, ceramics, glasses, polymers, compounds, composites and other materials to meet the research, development and specialist production requirements of science and industry. The Company has an extensive range of 70,000 catalogue products in multiple forms available off the shelf, most subject to free delivery within 48 hours and with no minimum order quantities. Goodfellow also offers a comprehensive range of bespoke processing services, effectively operating as an extension of a customer’s production team in order to develop custom-fabricated components in any quantity required.

Goodfellow’s in-house team comprises fellow scientists and engineers with extensive knowledge of materials and processing. Through their technical expertise and a supporting range of specification tools, the Company has built an unrivalled reputation for helping to find solutions to even the most challenging of research problems. All of their products are underpinned by ISO 9001 quality accreditation.

New material, High Density Calcium Silicate has been launched by Goodfellow to ensure customers still have access to a material which has high-quality thermal and electrical insulation characteristics for high temperature applications following the discontinuation of Duratec® 750. Relevant applications include use in chemical plants, refineries and electric power plants.

High Density Calcium Silicate has a maximum service temperature of 1000 oC, is machinable and is asbestos free, which means it is non-hazardous.

The new material can be machined to tight tolerances using carbide-tipped tooling. As was the case with Duratec® 750, High Density Calcium Silicate is offered as machined components as well as sheets and rods.
