SPLICED GASKETS
拼接垫片
For fabricated gaskets with a minimum inside diameter of 2 inches (51 mm), extruded strips can be spliced to form a continuous seal. Spliced gaskets offer cost savings over molded gaskets without sacrificing performance. In particular, spliced hollow extrusions yield lightweight, low closure force gaskets at considerable savings. For solid silicone extrusions, the splice is often as strong and as resilient as the gasket itself.
对于内径最小为2英寸（51mm）的加工垫片，挤出条可拼接形成连续密封。拼接垫片相对于模制垫片可节约成本而不会牺牲性能。特别是，中空挤出件拼接的轻质、低闭合力垫片具有相当大的节约。对于实心硅胶挤出件，接合处通常与垫片本身同样强壮且有同样弹力。
Gaskets spliced by Chomerics or our Authorized Fabricators feature a vulcanized joint, formed under heat and pressure, that ensures functionality and a more uniform joint compared with adhesive bonding. For use with retention grooves, refer to Table 6 for recommended inside corner radii.
Chomerics 或我们的授权加工商拼接的垫片具有硫化接缝的特点，在加热加压下成型，保证了其功能性，并且与粘结剂粘接相比接缝更统一。对于带固定沟槽的使用情况，推荐内角半径见表6。
Spliced gaskets with an inside diameter smaller than 2 inches (51 mm) are available for round, oval or “D” shaped profiles for a nominal set-up charge. Contact Chomerics’ Application Engineering Department for details.
内径小于2英寸（51mm）的拼接垫片，可采用圆形、椭圆或“D”形轮廓，收取少量机器设置费。详细情况联系 Chomerics 的应用工程部。
FRAME ASSEMBLIES
骨架组合件
Chomerics fabricates complete frame/gasket assemblies either in their entirety or using customer-supplied parts. These incorporate vulcanized joints and miters, and often more than one gasket material or profile. With experience ranging from handheld devices to floor-standing equipment, size is not a limitation.
Chomerics 制作成套骨架/垫片组合件，或完整制作，或利用用户提供零件。这些会引入硫化接缝及斜接缝，通常多于一种垫片材料或剖面形状。我们具有从手持装置到落地设备的使用经验，尺寸并不是限制。
BONDED GASKETS
粘接垫片
Similar and dissimilar compositions and profiles can be bonded in parallel for special requirements. Capabilities include bonded-in compression stops, holes and other features.
相似或不相似成分及剖面形状的制品可以针对特殊要求而平行粘接在一起。能够做出粘合压缩挡面、孔及其它特征。

SMALL, DIE-CUT GASKETS FROM FLAT EXTRUSIONS
扁平挤出件的小型、模切垫片
Standard rectangular extrusions up to 2 inches (51 mm) wide can provide an economical means of producing die-cut gaskets for some applications.
宽度小于2英寸（51mm）的标准矩形挤出件可为某些应用提供经济的模切垫片生产方法。
PRESSURE-SENSITIVE ADHESIVE (PSA)
压敏粘结剂（PSA）
Chomerics’ extruded conductive elastomer EMI gaskets are available with non-conductive pressure-sensitive adhesive (PSA) tape for permanent attachment. Typical properties for this adhesive are shown in Table 5 below. The acrylic pressure-sensitive adhesive does not appreciably affect the through-flange resistance of the EMI gasket. Non-conductive PSA is preferred over conductive PSA because it exhibits higher peel strength than conductive PSA.
Chomerics 的挤出导电橡胶抗电磁干扰垫片可一同提供非导电压敏粘结剂（PSA）胶带用于永久结合。这种粘结剂的典型特性如下面表5所示。丙烯酸压敏粘结剂对于电磁干扰垫片的穿透法兰抵抗性没有一点影响。比起导电PSA应优先使用非导电PSA，因为它比导电PSA具有更高的剥离强度。
AVAILABLE WIDTHS OF PSA, INCH (MM)
PSA 可用宽度，英寸（mm）
0.050 (1.27)
0.090 (2.29)
0.100 (2.54)
0.125 (3.17) min. recommended
0.125 (3.17) 最小推荐使用
0.160 (4.06)

0.250 (6.35)
0.300 (7.62)
0.375 (9.53)
0.500 (12.70)
In general, pressure-sensitive adhesive requires a minimum of 0.125 inch (3.17 mm) flat mating surface. For this reason, Chomerics does not ordinarily supply PSA on solid or hollow O strips.
总体上，压敏粘结剂需要最小0.125英寸（3.17mm）的平配合表面。因此，Chomerics一般不在实心或中空O形条上提供PSA。
