Basalt Tadpole Seals help increase product strength, safety.

Press Release Summary:




Made from melted basalt rock without any additives, tadpole seals feature 100% recyclable, basalt woven fiber to offer environmentally friendly alternative to fiberglass materials. Properties include 2,500–3,000 mpa tensile strength; acid/alkali, abrasion, and chemical resistance; and thermal conductivity of 1.44–1.46 W/m-k. With 2,642°F melting point, this non-hazardous, non-combustible, fire-resistant material operates up to 1,200°F (continuous) and 1,800°F (intermittent).



Original Press Release:



NEW PRODUCT - Basalt Tadpole Seals



Basalt woven fiber is an environmentally friendly alternative to fiberglass materials. With excellent tensile strength, excellent resistance to Acid and Alkali, High abrasive resistance and a high melting point. Basalt is originates from igneos rock (volcanic, molten lava) and is 100% Recyclable.



Overview

- Basalt is a volcanic rock that has natural fire resistant components. The use of basalt in fibers is a potentially stronger, safer product than traditional glass fibers.

Manufacturing

- No secondary materials (unlike glass fibers)

- More abrasive so harder on equipment



Basalt vs. Glass Fibers

The main difference is that E-Glass is made from a complex batch of materials, wheras Basalt Fiber is made from meltingbasalt (volcanic) rock with no other additives need. This makes Basalt-based matererials very environmentally firendly and non-hazardous.

Basalt Benefits compared to standard Fiberglass Include:



• 20-25% Higher Tensile Strength

• 10-15% Higher Tensile Modulus

• Higher Melting Point

• Higher Operating Temperature

• Extended Temperature range

• Non-combustable, Fire-Resistant Material

• Superior Abrasion Resistance

• Greater Thermal COnductivity

• Better Chemical Resistance, (4.5% better)

• Low water absorption properties

• Superior adhesion characteristics for coating

• resistance to electromagnetic radiation



- Fire-blocking tests performed by Basaltex placed its basalt fabric in front of a Bunsen burner, placing the yellow tip of the flame in direct contact with the fabric. The yellow tip reaches temperatures of 1100°C to 1200°C (2012°F to 2192°F) and causes the fabric to become red hot, similar to a metal fabric. When exposed to the flame, basalt fiber maintains its physical integrity for extended periods of times, but the company found that a fabric made of E-glass with the same density can be pierced by the flame in a matter of seconds.
