Safety Fuse (Polycoated)

 

Polycoated fuse is a highly water resistant fuse in which gunpowder is wound in jute yarn and coated with a layer of bitumen. This base fuse is then wrapped in a paper tape tube and is provided with a continuous coating of Low Density Polyethylene (LDPE) or Polyvinyl Chloride (PVC).

The LDPE / PVC coating makes the safety fuse water resistant and thus suitable for use in wet conditions. The fuse is given a red or yellow colour by default but it can be changed as per the users requirement.

Polycoated Safetyfuse is available as a CE marked product and is exported by us regularly to countries in South East Asia, Middle East & Western Europe.

Although every effort is made to insure uniform burn times, safety fuses are subject to variation depending on conditions and should be used with adequate safety margins.
