Chemtane 2

The most efficient and performing gas for cutting and heating with oxygen
Chemtane 2

Chemtane 2 is  a new generation additive for LPG and LNG  formulated to substitute acetylene in oxy-cutting, welding and industrial heating outperforming it. CHEMTANE 2 is successfully being used in numerous industrial manufacturing and fabrication environments with repeated success. This product is utilized in cutting, scarfing, gouging, brazing, soldering, flame hardening, thermal spraying and flame coating, among other processes.

Details and comparisons

Discover the history, comparative properties and possibilities of Chemtane 2

Its origins

CHEMTANE 2 is a cutting fuel developed over 17 years ago by Chemtane Energy, LLC.. During the past decade, the company  has devoted extensive resources to developing and refining the blending of its chemicals. The result is a new generation cutting fuel that is more economical, faster, and safer than acetylene. This product’s performance offers the consistency and reliability not usually associated with other products.

Chemtane 2 vs Acetylene

Chemtane 2 increases flame temperature up to 3315ºC, which is higher than acetylene. Chemtane 2’s secondary flame being longer and hotter allows a much more comfortable, quick and easy job.

It is safe, with minimum slag and weldback. It burns clean, without soot or smoke. It has very narrow explosive limits and it is stable, not sensitive to shock.

Chemtane 2 is unexpensive; the cost per unit is much lower than acetylene’s.
No rent is being charged for the cylinders.
Less consumption of fuel and oxygen.
Minimizes system rebuilds.
Less storage space is needed.
It is environment friendly, no pollutants are emitted during its manufacturing, it does not contain any acetone and it burns clean.
It contributes to energy saving since less fuel and oxygen are required.
Less labor is required due to reduced handling of materials.

Chemtane 2 vs Propane

Chemtane 2’s flame temperature in oxygen is about 800ºC higher than propane’s. This allows a much quicker job with a reduction of about a 42% of oxygen.

This additive is much more profitable than propane. In decreasing time we obtain more production, less consumption of fuel and oxygen and we reduce labor costs.
