In widespread use for automobiles and interiors

Daikyo Chemical's VIGOL FV series, non-halogen flameproofing agents for textiles, is in high demand for flameproofing agents for car seats, amid worldwide strengthening of environmental restrictions.

Daikyo Chemical has been a manufacturer of functional finishing agents mainly for flameproofing, creating advanced products with high added value through its high level of technology from its establishment in 1947.

Our flameproofing agent "VIGOL" is widely used for antiflaming in various areas from JR trains to first-class hotels' interiors, architectural materials and automobile interiors.

Daikyo Chemical's flameproofing agents are certified and registered as flame retardant products under the Fire Defense Law by the Japan Fire Retardant Association.

Today environmental control is getting tighter worldwide for health measures. In response to this, Daikyo Chemical has developed VIGOL FV Series, non-halogen flameproofing agents for textiles, and engaged in global-scale promotion including obtaining patents.

Flameproofing properties of non-halogen flameproofing agent VIGOL FV-1010 are shown in Fig.-1 below (Micro Burner method).

Flameproofing agents for automobile fabric.
Non-halogen types will become mainstream in future.

Automobile fabrics are required to have various properties not only flameproofing, but fastness to light, rubbing and chemicals, and flameproofiing agents which meet these requirements in good balance are necessary.

Amid the strengthening of restrictions on chemical substances, HBCD (1,2,5,6,9,10- hexabromocyclododecane), a main component of halogen flameproofing agents which has been used in the automobile area, has been designated as a Type 1 Monitoring Chemical Substance in Japan and the future use of it will be oriented toward the strengthening of restrictions. This trend seems to be expanding overseas as well.

Daikyo Chemical's VIGOL FV Series, non-halogen flameproofing agents for textiles, now has 4 items lined up, FV-1010, FV-1030, FV-2010 and FV-3010 (new development) for a wide range of uses for flameproofing of automobile fabrics and interiors.

* There are partial restrictions on FV-3010 due to the product being newly developed. Please consult separately about this product.

Phosphate ester amide is the raw material of FV-1010 and 1030, aromatic condensed phosphoric acid ester is of FV-2010 and that of FV-3010 is phosphorus-nitrogen compound.

Characteristics of VIGOL FV Series, non-halogen flameproofing agents for textiles, are shown in the Table-1 below.

Table-1 Characteristics of VIGOL FV Series, non-halogen flameproofing agents for textile

FV-1010 patented in Japan and China.
Examination requests currently under process in EU, US, Korea and Australia.

FV-1010 is capable of not only in-bath treatment during dyeing, but padding and back-side finishing with sprays and rolls. FV-1010 has already been patented in Japan and China. Examination requests for this product have been submitted in the EU, the US, Korea and Australia.

FV-1030 and 2010 are for in-dyebath treatment and FV-3010 is for padding.
FV-1030 consists mainly of the same components as FV-1010, but has specially improved high-temperature dispersibility and machine stability of FV-1010. FV-2020 has been patented in Japan and FV-3010 is currently under patent application.

Overseas registration status of VIGOL FV Series component is shown in the Table-2 below.

Table-2 Overseas registration status of VIGOL FV Series components

As shown in Table-2, there is no problem for any agents in the FV series to be exported and used in China as they are registered as Existing Chemical Substances.

With a view to expanding promotion for automobile fabrics, the registration of FV-1010 and 1030 under TSCA is currently under process in the US.

FV-2010 is can be used in the EU as its components are listed in the European Inventory of Existing Chemical Substances, as well as in the US and China.

Not causing hydrolysis in hot and humid conditions.

Daikyo Chemical's VIGOL FV series (FV-1010, FV-1030, FV-2010 and FV-3010), non-halogen flameproofing agents for textiles, produce less chemical reaction such as hydrolysis even in hot and humid conditions and less aging degradation on fabrics, which contributes to widespread use in antiflaming curtains, fire-proofed wall materials, automobile fabrics and fire-retardant car seats. Changes in tearing strength of VIGOL FV-1010 and another company's product with the jungle test are shown in Fig.-2.

Capable of flameproofing in-dyebath, padding and back-side finishing.

Automobile fabrics are required to meet various strict needs such as not only flameproofing, but fastness to light, rubbing and chemicals, and flameproofiing agents which fulfill those requirements in good balance are necessary.

Daikyo Chemical's VIGOL FV Series, non-halogen flameproofing agents for textiles, has high resistance to hydrolysis despite being phosphorous flameproofing agents, and produce no hydrolysis when used during dyeing, which makes them the most suitable for use in automobile fabrics.

When fabrics are exposed to water, stains (water spots) are produced on lines between wet parts and dry parts after being dried, for ones flameproofed with conventional hydrosoluble flameproofing agents like guanidine phosphate. For fabrics finished with VIGOL FV Series, no stains (water spots) like those mentioned above are produced even if they are exposed to water since the main components are non-hydrosoluble compounds.

VIGOL FV Series has a feature to make negligible contamination on drying machines like setters because of low sublimation properties.

VIGOL FV Series is not only capable of being used for flameproofing in-dyebath treatment for automobile fabrics and interiors, but also for padding and back-side finishing with sprays and rolls.

Flameproofing results of automobile fabric finished with in-dyebath treatment with VIGOL FV-1010 and 1030 are shown in Fig.-3, and ones with the kiss-roll method in Fig.-4.
