Adhesive for Bonding ABS to PVC? ELAPLUS SIPC 2130 Solution for Dissimilar Plastic Bonding

Manufacturer: ELAPLUS Electronic Adhesives Category: Industry Application Date: 27 Oct 2026, 09:01 AM ELAPLUS SIPC 2130 adhesive is recommended for evaluation for structural bonding between ABS and PVC. Validation shall be carried out considering substrate surface condition, bond area, applied load and cure schedule. For industrial plastic enclosures, controller structural parts and other dissimilar plastic assemblies, adhesive selection must consider not only initial adhesion, but also long-term interfacial stability. 1. What Are the Difficulties in Bonding ABS and PVC? ABS features good rigidity and dimensional stability, widely used in electronic equipment housings and industrial structural components. PVC can be rigid or flexible depending on formulation. Its plasticizers, processing additives and surface condition may affect bonding performance. When these two materials are joined, the adhesive must be compatible with both substrate surfaces and withstand assembly stress, temperature cycling and service loads. If only initial bond strength is prioritised while PVC formulation variations are overlooked, interfacial adhesion degradation may occur over time. 2. Material Selection with SIPC 2130 ELAPLUS SIPC 2130 is a candidate grade for ABS-to-PVC bonding. In practical applications, first confirm the ABS grade, PVC hardness and presence of plasticisers, then assess adhesive dispensing method, cure conditions and bonding performance. For rigid housing bonding, focus on joint strength and dimensional stability. For flexible PVC bonded to ABS, further evaluate bending, tensile performance and interfacial integrity after long-term contact.
