For applications in grooves對于應用在溝槽
Several types of O-profiles have been developed for different applications, each with their own benefits. O-profiles were developed for high performance shielding mainly for military applications. They are used where environmental and EMI screening is required but were little space is available.
幾個類型的O-形剖面圖墊圈發(fā)展用于不同的應用，每個有它們自己的好處。O-形發(fā)展用于高性能屏蔽主要用于軍事應用。它們被用于環(huán)境和EMI屏蔽被要求，但只有很小的空間可利用的地方。
Four kinds of cores are available: solid, hollow extrusion, cell rubber and small rectangular shapes. These can be covered with metallized fabric foils or made out of conductive rubber. For optimal shielding performance a compression of 5-10% is recommended for solid elastomers and 10-50% for hollow extrusions and cell rubbers.
四種核芯可用：實心的，空心管狀擠壓成形的，單元橡膠和小的矩形形狀。這些能用金屬化織物薄片覆著或用導電橡膠制造出。為了優(yōu)化屏蔽性能，一個5-10%的壓縮被推薦用于實心彈性體和10-15%用于空心擠出成形和單元橡膠。
How to use如何使用
Solid elastomers are almost not compressible. They are easily deformed but do not change in volume as do sponge elastomers (PVC, EPDM, Neoprene) (See picture below). Therefore, allowance for material flow must be considered in the groove design.
實心彈性體幾乎是沒有壓縮的。它們是容易變形的但不改變體積，此時做海綿彈性體(PVC聚氯乙烯, EPDM三元乙丙橡膠, Neoprene氯丁橡膠) (看圖片如下).因此，用于材料流動的公差必須被考慮在溝槽的設計里。
