Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of fire-resistant bags, it is recommended to prioritize checking key technical parameters such as fire resistance limit and expansion coefficient to ensure that they match the fire-resistant sealing requirements of building cable holes or pipeline penetrations.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. For example, application cases of flame retardants in petrochemical, power, and other scenarios can be used as screening criteria.
  • Different application scenarios, such as high-rise building shafts or industrial equipment cable trenches, have differentiated requirements for the weather resistance and filling density of fire-resistant packages. When purchasing, it is necessary to clarify the usage environment.
  • The size specifications of the flame retardant package need to be adapted to the actual sealing space. If it is too small, it may result in residual gaps, while if it is too large, it will affect construction efficiency. It is recommended to calculate the amount in advance based on the engineering drawings.

Knowledge Base

Q

How to choose a flame retardant package Flame retardant packaging is a product used for fire prevention and extinguishing. Its main feature is that it can maintain integrity under high temperature and flame action, and isolate the transfer of air and heat, thereby achieving the purpose of extinguishing and preventing the spread of fire. When choosing a fireproof bag, in addition to considering the size of the item, the quality of the fireproof material should also be taken into account.

Q

Fire resistant fiberglass bag is a type of bag that is high-temperature, fire-resistant, and flame-retardant, widely used in various occasions. This article will introduce the characteristics and application fields of fire-resistant fiberglass bags, providing convenience for relevant personnel.

Q
