Microcord is used for ignition of consumer fireworks and other pyrotechnics and is also known as ‘pyrotechnic fuse’. It is a safe, reliable and easy to use means of initiation. Microcord is also used to create delays in the rate of firing multiple fireworks linked together, or for firing multiple tubes / cakes in display fireworks to create a burst train.
Our microcord is usually 1.8 – 3.0 mm thick with a black powder / gunpowder core. The standard burning speed is 100 sec/mtr. We also manufacture microcord in various burning speeds and diameters, as per the users’ requirement.
The construction consists of multiple layers of yarn wrapped around the inner gunpowder core and a top layer of nitrocellulose lacquer to bind the fuse together, and provide water resistance, higher shelf life and stiffness.
Microcord is easily distinguished from safety fuse as microcord produces significant sparking flame throughout the length when burning. It is also capable of cross ignition / lateral transmission of flame and is mostly fully consumed as it burns instead of leaving a significant carcass.

FAQs - Microcord Product
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 standard packing 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.
Our production and QC processes are certified under ISO 9001:2015 quality management systems by TÜV SÜD. Our product Visco Fuse / Micro Cord has EX Registration for USA and CE certification and ADR classification approval for Europe.
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.
