| Rulon LR |
|
|
| Rulon LR:
Material autolubricado con caracteristicas de baja deformación, recomendado para aplicaciones de fricción contra superficies duras.
Químicamente inerte.
Color rojo |
| Rulon #174; LR es de un color Rojizo conocido por versatibilidad. Es practimanete inerte a los agentes químico. De las sustancia quimicas comerciales el Sodio y el Fluor a elevada temperatura y presión muestran signos de ataque al material.
Para uso continuo y no lubricado en Rulon LR se muestra eficaz en el orden de 10000 pv (psi-fpm)en continuo, en otras condiciones en uso discontinuo |
