What are our sponge standards?
Ordinary Sponge
An ordinary sponge is the light yellow sponge that we often see. They can be found in various places. Seats, office sofas, tablecloths, mattresses, etc. It can be said that they have the lowest threshold for use, are very soft, and have average elasticity. If you use them as office chairs, the price must be very cheap. If you don't pursue health and comfort, you can choose.
Molded Foam
Sponge is made of polyurethane and processed through multiple processes. The biggest characteristic of a sponge is that its density can be adjusted according to needs. If used on seat cushions, office furniture manufacturers can choose according to the healthiest density to ensure comfortable seats without affecting health. Of course, its price will also be much higher than other sponge filled office chairs.In addition, foam density will affect all aspects of foam performance, such as hardness, durability and insulation performance. The following are some potential effects of different foam densities:
Hardness: foam density will affect the hardness of foam products. Generally, the higher the density of foam, the stronger the foam. For example, high-density foam is often used in furniture cushions because it provides strong support.
Durability: Compared with low-density foam, high-density foam usually has greater durability and can withstand more use. This is because high-density foam has more material in a given volume, which makes it unlikely to decompose over time.
Insulation: The density of foam will also affect the insulation performance. High density foam has more air pockets per unit volume, which means that it can capture more heat and provide better insulation effect than low density foam.
Weight: high-density foam is usually heavier than low-density foam, which may be a consideration for some applications. For example, if weight is an issue, lower density foam can be used in the product to reduce its total weight.
Cost: Generally, high-density foam is more expensive than low-density foam. This is because it requires more materials for production and has greater durability.
However, in order to gain more customer trust in the production of office chairs, Orcco strictly controls the quality of office chair production, one of which is CA TB117-2013 certification.
What kind of testing is required for TB117-2013?
- TB117-2013 includes smoldering tests on fabrics, fillers, paving, and barriers (if used), similar to the current voluntary industry standard UFAC/NFPA 260. There is no open flame test.
- Each component has been tested with standard fabric and/or foam components.
- For fabrics that fail the smoldering test, the compliance barrier foam can be used between fabrics. Polyester cotton wool is an example of a material that typically meets barrier requirements.
Benefits
- Consumers: Although the new standard can be achieved without flame retardants, it does not prohibit the use of flame retardants. Consumers who want to reduce household exposure to flame retardants can search for TB117-2013 labels on furniture and verify with retailers that the product does not contain flame retardants.
- Retailers: Consumer demand for non flame retardant products is increasing. Extensive media coverage and the actions of the Environmental Protection Agency (EPA) have made consumers and retailers aware of concerns related to flame retardant chemicals.
- Manufacturer: If exposure to harmful flame retardant chemicals is reduced or eliminated, employees' workplaces will be safer and healthier.
- Liability: In 2012, after the furniture flame retardant "chlorinated Tris" or TDCPP was included in California Proposition 65, the manufacturer was sued. For products without added flame retardants, the liability issues of TDCPP and other flame retardant chemicals that may be prohibited or listed have been reduced.
- Fire safety: The suffocation standard required by TB117-2013 is a strict standard that can ensure high-level fire safety for ordinary fire sources
