求翻译：由于密封圈采用新型非金属材料制成，混合综合性能好，具有经受长期高温、高压而不丧失弹性的性能，况且柱塞与密封圈之间的接触面积大。因此密封可靠、经久耐用。是什么意思？

Seal with the new non-metallic materials, mixed comprehensive performance, has withstood the long-term high-temperature, high pressure without losing the performance of the flexible Moreover, the large contact area between the plunger and seals. Therefore, sealing, reliable and durable.

The seal in a new non-metallic materials, can be better integrated, mixed with a high temperature, high pressure experienced long-term, without losing flexibility of performance, and plunger with the sealing ring the contact area between the. It is therefore reliable and durable seal.

Because the seal packing collar uses the new nonmetallic material to make, the mix overall performance is good, has the undergoing long-term high temperature, the high pressure does not lose the elastic performance, moreover between the plunger and the seal packing collar contacted area is big.There

Due to the sealing rings made using new type non-metallic materials, mixing good comprehensive performance, has suffered long-term performance of high temperature, high pressure without loss of flexibility, and large contact area between the piston and seal rings. Reliable, durable seal.
