Safety Fuse – Polycoated
‘Tiger’ Safety Fuse - Polycoated
Polycoated safety fuse is an explosive accessory used to initiate plain detonators (blasting cap) in opencast mines and quarries. It offers high water and abrasion resistance and a better shelf life.
In polycoated safety fuse, gunpowder is wound in yarn and coated with a layer of bitumen. For making the fuse highly water resistant, it is encased in a plastic tube.
Polycoated safety fuse is suitable for use in damp as well as dry conditions. The polycoated fuse that we provide is usually coloured red or yellow, but it can be customized as per the user’s requirement.
“Tiger” brand Polycoated Safety Fuse is a CE-certified export quality product. Our commitment to product quality and customer satisfaction has led to fruitful, long-term relationships with many consumers worldwide.

FAQs - Safety Fuse Product
The length of the safety fuse is chosen and cut according to the required time delay. An end of the safety fuse is inserted and crimped into the plain detonator, while the other end is left open for ignition. A safety match or igniter is used to ignite the open end, and the fuse slowly burns towards the plain detonator. The slow burning gives the blaster time to retreat a safe distance from the blast site. Once the fire in the safety fuse reaches the plain detonator, the detonator explodes and initiates the explosives with which the plain detonator is used.
Safety fuse is generally used for Blasting purposes in mining, quarries and construction work with plain detonators although time fuse is somewhat similar to safety fuse and still used for fireworks.
Visco fuse / micro cord / cannon fuse is used to ignite fireworks and other pyrotechnics. They have different characteristics and usage should be evaluated thoroughly.
Within India - 1 Box as per the approved Packing Code of PESO and maximum as per license held.
Outside India – An order quantity below 100 Kilometers (100,000 metres) is rarely economical due the fixed export and freight overheads. However, we can consider a lower quantity in case of specialized products and in case the buyer is agreeable to higher costs.
Currently our CE certification for safety fuse is valid for diameter 5.0 to 6.0 mm ± 0.3mm
FAQs - Transport & Shipping
For international transport to Europe and Africa and Southeast Asia, we can send containerized shipment by sea to certain countries / ports which handle HAZ cargo and onwards transportation can take place by road as per local laws and norms. We can also air freight to many countries / airports subject to local approvals and acceptance by airlines.
Due to lengthy process of licensing, permissions and transit permits and infrequent availability of IMO vessels and congestions, even after production it may take around 15-25 days for the shipment to move from India.
