Tents, awnings and room dividers

Apyrum can be used as a flame retardant for tenting material, room dividers, awnings, and other textile applications where fire class SIS 650082 can be achieved. The treatment is carried out by impregnating the fabric after which it can be treated by a water-proofing impregnating agent.

The treatment has been developed for use with woven cotton and can be applied to both new and older fabric.

The application process

When treating tenting material or awnings, the fabric should be impregnated with Apyrum. Depending on the size and form of the fabric, as well as any other prerequisites, other methods of application may be chosen for use.

  • The fabric must be clean and dry.  
  • If the fabric can be spread out on the floor, the use of a scouring brush or rubber scraper is the most expedient way to apply Apyrum. Spraying the fabric with Apyrum can also work. In certain cases, it might be necessary to soak the fabric in a tub or vat.  
  • Dry the fabric after it has been treated. You will attain the best results if the fabric is stretched and held taut.
  • Thereafter, eventually waterproof the fabric by applying a water-proofing agent that provides weather resistance 

In order to decide the amount of flame retardant needed, it is necessary to carry out a test in advance in order to determine the correct load and method of application.

Choice of Apyrum product

The product that is used for treating tenting material and cotton awning fabric is the water-based product, Apyrum 201 Liquid; a liquid product consisting of water and Apyrum in the form of a water-soluble salt.

The product is adapted to penetrate into the tenting material. The amount of active substance is adapted through optimization and takes into consideration the fire properties of the material and the fire requirements demanded thereof.

The properties of the product are:

  • Density: 1,4 g/ml pH: 7
  • Viscosity: Approximately the same as water
  • Packaging for delivery: Cans, drums, 1000 litres IBC containers  

Environmentally friendly

Apyrum is classified as environmentally friendly. Apyrum contains no boron compounds or halogenated substances.

Apyrum is able to replace flame retardants that are dangerous for health and the environment while at the same time improving the fire protection.

Fire testing

Cotton tent material treated with Apyrum meets the fire standard SIS 65 00 85.

Facts about SIS 65 00 82 – Flame proofness

  • Textiles , determination of flameproofness of fabrics according to SIS 65  00 82.
  • Main field of application: The product can be classified according to Boverkets Allmänna råd 1993:2 Utgåva 2 after testing.  The class is designated “material difficult to ignite”.
  • The test can be the basis for the application for approval with supervising third-party control. The method measures the ignitability of all kind of fabrics, textiles and building materials up to 3.5 mm thickness.
  • Examples of products that can be tested in this method: All types of textile materials and building materials with a thickness up to 3.5 mm.

Here’s how the test is executed:

  • Test specimens shall be charged in both warp and weft direction. The same warp and weft threads must not be included in several test cells.
  • Testing shall be conducted in a test chamber which is open at the top and the bottom has an opening at the front.
  • The conditioned specimen is hung vertically and held in place by clamps. The impactor is ignited at the hem with a gas burner.
  • When the flame is removed, the time until the specimen ends to burn and glow is measured. Damage length is measured.

Deflamo has its own laboratory and equipment to carry out fire testing by this method for development purposes.
