Document Type and Number:
Japanese Patent JP2005313641
Kind Code:
A
Abstract:
To provide a production method of tubular articles of a thermoplastic elastomer which have a thin wall and a soft and flexible closed-end.
The method employed to lower the coefficient of elasticity of the tubular articles of a thermoplastic elastomer which have a thin wall and a closed-end comprises a process to extend the above tubular article on a shaping mandrel and a process to heat the above tubular article and the mandrel at a temperature of 100-125°C during a sufficient time to reduce the coefficient of elasticity of the above thermoplastic elastomer.
