SVR CV50 is a medium-soft constant-viscosity natural rubber grade designed for stable Mooney viscosity and easier processing compared with higher-viscosity CV grades such as SVR CV60 or SVR CV70. With Mooney viscosity controlled at 50\u00b15, SVR CV50 is suitable for rubber compounds requiring easier mixing, smoother flow, and consistent batch processing.<\/p>\n
Easier Mixing & Compound Incorporation:<\/strong> Mooney 50\u00b15 provides lower viscosity than SVR CV60, helping reduce mixing resistance in softer compound designs.<\/p>\n<\/li>\n Stable Processing Behavior: <\/strong>Controlled-viscosity production helps reduce batch-to-batch variation during mixing, extrusion, calendering, and molding.<\/p>\n<\/li>\n Flexible Formulation Window:<\/strong> Suitable for compounders that need a medium-soft natural rubber grade between SVR CV40 and SVR CV60.<\/p>\n<\/li>\n<\/ul>\n SVR CV50 (TSR CV50) is manufactured according to TCVN 3769:2016, with APT Rubber applying tighter internal control targets before shipment release.<\/p>\n Get the latest FOB\/CIF quotation and available shipment schedule.<\/p>\n Widely used by tire manufacturers, rubber compounders, and industrial rubber processors requiring stable Mooney viscosity and consistent processing performance.<\/p>\n Compare key processing characteristics before selecting the right SVR grade for your compound requirements.<\/p>\n Q: Is SVR CV50 the same as TSR CV50?<\/strong> Yes. SVR CV50<\/strong> and TSR CV50<\/strong> both refer to a constant viscosity natural rubber grade with a typical Mooney viscosity target of 50 \u00b1 5<\/strong>. \u201cSVR\u201d is commonly used for Vietnamese Standard Rubber, while \u201cTSR\u201d refers to Technically Specified Rubber in international trade.<\/p>\n For buyers, both terms are used to describe a controlled-viscosity natural rubber grade suitable for manufacturers that require stable processing performance.<\/p>\n<\/p>\n Q: What is the typical Mooney viscosity of SVR CV50?<\/strong> SVR CV50 is produced with a typical Mooney viscosity target of 50 \u00b1 5<\/strong>. This controlled viscosity range helps manufacturers improve consistency during mixing, extrusion, molding, and compounding.<\/p>\n For procurement teams, this means SVR CV50 is suitable when the formulation requires a lower constant viscosity grade compared with SVR CV60, while still maintaining stable processing behavior.<\/p>\n<\/p>\n Q: How is SVR CV50 different from SVR CV60?<\/strong> The main difference is the viscosity target. SVR CV50 has a Mooney target of 50 \u00b1 5<\/strong>, while SVR CV60 has a Mooney target of 60 \u00b1 5<\/strong>.<\/p>\n Buyers usually choose SVR CV50 when their compound formulation requires easier processing, lower viscosity, or better flow characteristics. SVR CV60 is normally selected when a higher viscosity grade is required for the final compound design.<\/p>\n \n Q: What is the MOQ for SVR CV50? Are samples handled separately?<\/strong> Commercial export orders are usually handled by container quantity or agreed shipment lot. Samples are handled separately from commercial MOQ and may be arranged depending on stock, production season, and buyer requirements. Quotations are subject to available volume and APT final confirmation.<\/p>\n<\/p>\n Q: Does APT Rubber provide stable Mooney performance for SVR CV50?<\/strong> Yes. APT Rubber\u2019s controlled production process helps maintain stable Mooney performance for up to 6 months<\/strong>, subject to proper storage conditions.<\/p>\n This is important for manufacturers because viscosity fluctuation can affect mixing behavior, processing stability, and production consistency. Stable Mooney performance helps reduce unnecessary production adjustment and supports better batch-to-batch control.<\/p>\n<\/p>\n Q: Can SVR CV50 be supplied with EUDR or FSC\u00ae documentation?<\/strong> Yes. APT Rubber can supply SVR CV50 with EUDR-aligned traceability<\/strong> and FSC\u00ae certified supply<\/strong> depending on customer requirements, available raw material sources, and confirmed shipment programs.<\/p>\n For export buyers, APT Rubber can support procurement documentation such as COA, TDS, MSDS, packing list, invoice, certificate of origin, and additional compliance documents based on destination market requirements.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":" SVR CV50 (TSR CV50) Natural rubber<\/p>","protected":false},"featured_media":12982,"template":"","categories":[],"class_list":["post-6197","product","type-product","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/product\/6197","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/media\/12982"}],"wp:attachment":[{"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/media?parent=6197"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aptrubber.com\/vi\/wp-json\/wp\/v2\/categories?post=6197"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Viscosity Stabilization Process<\/h4>\n
