Abstract
The present disclosure is directed to an elastomeric cushioning element. The elastomeric cushioning element may include about 5 wt. % to about 50 wt. % elastomeric polymer network comprising a triblock copolymer having an average molecular weight of about 100,000 Da to about 500,000 Da; and about 50 wt. % to about 95 wt. % plasticizer disposed in the elastomeric polymer network. The plasticizer may include a first plasticizer having an average molecular weight of about 300 Da to about 800 Da and a viscosity at 40° C. of about 20 cSt to about 10,000 cSt.
Claims19
An elastomeric cushioning element comprising:
- about 5 wt. % to about 50 wt. % elastomeric polymer network comprising a triblock copolymer having an average molecular weight of about 100,000 Da to about 500,000 Da;
- and
- about 50 wt. % to about 95 wt. % plasticizer disposed in the elastomeric polymer network;
- wherein the plasticizer comprises a first plasticizer having an average molecular weight of about 300 Da to about 800 Da and a viscosity at 40° C. of about 20 cSt to about 10,000 cSt;
- wherein the plasticizer further comprises a second plasticizer having a molecular weight of about 200 Da to about 500 Da and a viscosity at 40° C. of about 2 cSt to about 20 cSt.
A method of forming an elastomeric material comprising:
- dissolving an elastomeric polymer network comprising a triblock copolymer having a molecular weight of about 100,000 Da to about 500,000 Da in a solvent to form a mixture;
- adding a plasticizer to the mixture, the plasticizer having a molecular weight of about 300 Da to about 800 Da and a viscosity at 40° C. of about 100 cSt to about 10,000 cSt;
- and
- removing the solvent from the mixture to form the elastomeric material.
