Injection molded parts were made of unfilled PP, PP with the addition of the foaming agent
and PP + talc without/with the foaming agent
You're taking 7.5 cents' worth of material out by adding 3 cents' worth of a foaming agent
, and you're netting 4.5 cents saved."
Foam mat drying is carried out by transforming liquid and semisolid materials into stable foam by incorporation of air and a foaming agent
. It is a good option to shorten drying time and to retain product quality .
Fly ash was used as the aluminosilicate precursor and Si was added as the foaming agent
. The aim of this work is to record the combined effect of some significant synthesis parameters such as the Si foaming agent
content (% w/w fly ash based), the alkali type (R : Na or K), and the alkalinity (R/Al molar ratio) of the activation solution on the compressive strength, the apparent density, and the porosity development of the foamed fly ash-based geopolymers.
The composition includes 100 parts by weight of a blend of an olefin block copolymer and a rubber as a polymer matrix, 0.02 to 4 parts by weight of a crosslinking agent, and 1 to 6 parts by weight of a foaming agent
. The olefin block copolymer and the rubber are present in amounts of 50 to 80% by weight and 20 to 50% by weight, respectively, based on the total weight of the polymer matrix.
"Seawater contains a lot of organic matter, particularly alginates from seaweed which are a natural foaming agent
Sapnov, formulated with Quillaja saponaria, is a nonionic, water-soluble, 100% natural foaming agent
, according to the company.
Foamed gel, a complex mixed system, is formed by adding polymers and foaming agent
into water and stirring physically and mechanically under the function of nitrogen.
The biomass cushion packaging products are prepared through a special process, using plant fiber (straw fiber, bagasse fiber, etc.) and starch as the main raw material and plasticizer and foaming agent
as the additives.
Others had traces of 1,4-dioxane, a foaming agent
which is also believed to be a cancer risk for humans.
