Abstract
Disclosed herein are elastomer composites stored in a container or package. The composite is uncured and comprises at least one elastomer and at least one filler. The package or container comprises at least one wall surrounding the composite wherein the at least one wall comprises at least one oxygen barrier layer. Containers or packages having this oxygen barrier wall have an oxygen transmission rate of no more than 100 cm3/(m2·day·atm) at 23° C. and 0% relative humidity. Also disclosed are methods for storing elastomer composites with the packages or containers disclosed herein.
Claims43
A packaged elastomer composite, comprising:
- a sealed package containing the composite in an atmosphere having a partial pressure of oxygen of less than 10 kPa, wherein the composite is uncured and comprises at least one elastomer and at least one filler, wherein:
- the package comprises at least one wall surrounding the composite wherein the at least one wall comprises at least one oxygen barrier layer such that the package has an oxygen transmission rate of no more than 100 cm3/(m2·day·atm) at 23° C. and 0% relative humidity.

A method of storing an elastomer composite, comprising:
- sealing the elastomer composite in a container and storing the composite in the sealed container for a time period of at least 5 days, wherein:
- the elastomer composite is uncured and comprises at least one elastomer and at least one filler;
- and
- the container comprises at least one wall surrounding the composite wherein the at least one wall comprises at least one oxygen barrier layer such that the container has an oxygen transmission rate of no more than 100 cm3/(m2·day·atm) at 23° C. and 0% relative humidity.
A method of maintaining or enhancing at least one property of an elastomer composite or a compound formed from the composite, comprising:
- storing the elastomer composite in a sealed container for a time period of at least 5 days, wherein:
- the elastomer composite is uncured and comprises at least one elastomer and at least one filler;
- and
- the container comprises at least one wall surrounding the composite wherein the at least one wall comprises at least one oxygen barrier layer such that the container has an oxygen transmission rate of no more than 100 cm3/(m2·day·atm) at 23° C. and 0% relative humidity.
