Flexible slabstock foams high resilience

The resulting slate of polyols has been demonstrated in conventional flexible slabstock foam [143], viscoelastic foam [144], and high resiliency slabstock and molded foams [145],... 

Flame retardants are incorporated into the formulations in amounts necessary to satisfy existing requirements. There are four main types of flexible slabstock foam conventional, high resiliency, filled, and high load-bearing foam. 

Uses Surfactant for the production of high resilience flexible slabstock foams, esp. 

The steric effects in isocyanates are best demonstrated by the formation of flexible foams from TD1. In the 2.4-isomer (4), the initial reaction occurs at the nonhindered isocyanate group in the 4-position. The unsyinmeli ically substituted ureas formed in the subsequent reaction with water are more soluble in the developing polymer matrix. Low density flexible foams are not readily produced from MDi or PMDi enrichment of PMDI with Ihe 2,4 -isomcr of MDi (5) affords a steric environment similar to the one in TDI, which allows the production of low density flexible foams that have good physical properties. The use of high performance polyols based on a copolymer polyol allows production of high resiliency (HR) slabstock foam from either TDI or MDI. 

PHD polyols are successfully used for high resilience flexible PU foams (made by the cold cure process), for continuous slabstock flexible PU foams and for elastomers obtained especially by reaction injection moulding (RIM) technology. 

PIPA polyols, in spite of some disadvantages (tendency to foam shrinkage, and scorching), are used successfully for continuous slabstock flexible PU foams and high resilience foams (cold cure moulding process).
