Monomodal foamed polymeric compositions containing clay nucleating agents are described. The clays are preferably sepiolite, palygorskite/attapulgite, or combinations thereof. Also described are processes for forming the foamed compositions.

A long carbon fiber reinforced thermoplastic resin composition for foam injection and a molded article manufactured using the same are provided. More particularly, the thermoplastic resin composition and the manufactured molded article may be capable of improving component assembly and stability by minimizing deformation after foam injection molding. Such composition and molded article can be utilized as a component for a vehicle structure such as a panoramic sunroof frame. Also provided herein is a low-density polyamide-6 polymer comprising a long carbon fiber reinforcing agent, a thermoplastic elastomer, a silane-based coupling agent and a sodium phosphate nucleating. The polymer is suitable for foam injection. The thermoplastic resin composition and molded article made of said composition are light weight and economic feasibility as well as having high stiffness, durability, dimensional stability, and a desirable injection appearance.

The present invention is directed towards a method of stabilizing thermosetting foam blends such as polyurethane poly blends containing a blowing agent with negligible (low or zero) ozone-depletion and low GWP based upon unsaturated halogenated hydroolefins in which one or more ester is added to the thermosetting foam blends. The thermosetting foam blends typically in clued: polyol(s); surfactant(s); catalyst(s); flame retardent(s); organic acid inhibitor(s)/stabilizer(s); carbon dioxide generating agent(s). The addition of the one or more esters to the thermosetting foam blends was unexpectedly found to result in blends which were stable over time and the resulted foams have a uniform cell structure with little or no foam collapse.

Provided herein is a composition of a polypropylene resin with improved foaming capability with improved foaming capability, such as a polypropylene comprising a foaming agent master batch and a highly flowable polypropylene resin having non-controlled rheology. The resin composition exhibits excellent foaming quality and can be easily injected.

The polypropylene resin with improved foaming capability comprises a mixture comprising from about 50% to about 80% by weight of a polypropylene resin having a mean molecular weight of about 45,000 g/mol to about 180,000 g/mol, from about 15% to about 30% by weight of a fiber reinforcing agent, and from about 2% to about 20% by weight of a foaming agent.

This present invention discloses a halogen-free flame retardant polyolefin foam composite, which is comprises: 80-125 parts by weight of ethylene/vinyl acetate copolymer (EVA), 8-13 parts by weight of high density polyethylene (HDPE) or low density polyethylene (LDPE), 15-25 parts by weight of polyolefin elastomer (POE), 60-77 parts by weight of acid source material, 17-22 parts by weight of carbon source material, 8-11 parts by weight of gas source material, 1-8 parts by weight of retardant synergist, 5.5-8 parts by weight of composite foaming agent, 0.7-1.0 parts by weight of crosslinking agent, 4.0-5.5 parts by weight of plasticizer, 0.5-1.6 parts by weight of surface treatment agent, 20-35 parts by weight of compatibility, 6-14 parts by weight of inorganic filler, and 1.6-4.6 parts by weight of additive. This halogen-free flame retardant polyolefin foam composite has the advantages of good softness, flexibility, impact resistance, low density, low compressibility and deformability, good shock absorbability, and so on.

The present disclosure is directed to a composition and articles containing the composition. The composition comprises a foam and a plurality of gel particles dispersed in the foam. The gel particles comprise an olefin block copolymer and an oil.
