HR Refractory mortars are made to withstand high temperatures and harsh conditions. They create a strong, durable, and heat-resistant bond between refractory bricks or other heat-resistant materials in various
applications. They have the ability to withstand extreme temperatures without cracking or degradation. Below is the range of Refractory Mortars that HRWPL caters to its customers.
