This article sorts out the 2026 domestic liquid silicone rubber (LSR) brand ranking, comparing the raw material characteristics, production capacity, cost-effectiveness and applicable scenarios of four top brands including Hesheng, Xin'an, Dongyue and Jitai. It provides practical references for silicone product OEM enterprises in raw material selection and supplier cooperation, helping enterprises match the optimal LSR supply solution.
The global liquid silicone rubber (LSR) market is projected to reach $3.2 billion by 2027, with China accounting for 42% of global LSR production capacity as of 2026, driven by booming demand from medical devices, consumer electronics, automotive, and infant care sectors. For original equipment manufacturers (OEMs) sourcing LSR materials or end-to-end silicone product manufacturing services, selecting a domestic LSR supplier with consistent material quality, scalable production, and regulatory compliance is critical to reducing supply chain risks, lowering production costs, and accelerating time-to-market.
The 2026 domestic LSR brand ranking evaluates four leading players—Hesheng Silicon Industry, Xin’an Chemical Group, Dongyue Group, and Jitai New Materials—across core metrics including material performance, production capacity, regulatory certifications, OEM service scope, and cost competitiveness. This analysis provides OEM clients with data-driven insights to identify the most suitable partner for their specific product verticals, from high-precision medical components to cost-effective consumer silicone goods.
The suitability of an LSR supplier for OEM projects first hinges on the technical specifications of its base material portfolio, as different end applications require distinct mechanical, temperature resistance, and biocompatibility properties. The four leading brands have developed differentiated product lines tailored to high-growth sectors, with measurable gaps in performance parameters for specialized use cases.
For general-purpose LSR grades (Shore A hardness 30–70, the most widely used in consumer and industrial applications), the four brands meet baseline industry requirements, but exhibit variations in critical performance metrics that impact OEM production yield and end-product durability. Table 1 summarizes key test data for 50 Shore A standard LSR grades from each supplier, tested per ASTM D412, D2240, and D395 standards:
Hesheng’s standard LSR grade leads in mechanical strength and curing efficiency, a key advantage for high-volume OEM production where shorter cycle times directly reduce per-unit manufacturing costs. Jitai’s offering balances strength and low VOC emissions, making it a strong fit for consumer electronics applications where strict odor and volatile emission standards apply. Xin’an and Dongyue’s standard grades meet baseline requirements at a 5–8% lower raw material cost, making them suitable for price-sensitive consumer goods projects with less stringent performance demands.
For OEMs serving regulated or high-performance sectors, access to application-specific LSR grades is a non-negotiable supplier requirement. The four brands have invested in differentiated R&D for niche use cases, with varying degrees of portfolio depth:
Beyond material performance, OEMs prioritize suppliers that can support scalable order volumes, minimize lead times, and provide value-added services to reduce in-house production complexity. The four brands differ significantly in their upstream raw material integration, downstream manufacturing footprint, and end-to-end OEM support offerings.
Vertical integration of the organosilicon industrial chain is a key determinant of a supplier’s ability to stabilize raw material prices and avoid supply disruptions amid market volatility. As of 2026, the four brands’ capacity and integration profiles are as follows:
For high-volume OEM projects (annual LSR consumption >1,000 tons), Hesheng is the only supplier that can guarantee uninterrupted supply year-round, while Jitai is suitable for medium-volume (100–1,000 tons/year) projects with specialized material requirements. Xin’an and Dongyue are optimal for small-to-medium volume projects with lower supply chain volatility risk.
Many OEM clients prefer suppliers that can provide not just raw LSR materials, but also end-to-end manufacturing services including mold design, injection molding, post-processing, and quality testing, to streamline their supply chain and reduce administrative overhead. Table 2 compares the OEM service scope of the four brands:
Jitai’s low MOQ and precision mold manufacturing capabilities make it ideal for small-batch OEM projects such as medical device prototypes or high-end consumer electronics limited editions. Hesheng supports the highest volume orders with consistent quality, while Dongyue is the preferred choice for large-format automotive components such as EV battery pack seals that require high clamping force injection molding. Xin’an offers the most cost-effective OEM services for mid-volume consumer goods such as silicone kitchenware and baby pacifiers.
For OEMs exporting to global markets or serving regulated sectors, regulatory compliance is a critical screening criterion, while cost competitiveness directly impacts product profit margins. The four brands have varying levels of global regulatory coverage and pricing strategies tailored to different client segments.
Different end markets require distinct product certifications, and suppliers with pre-certified LSR grades can reduce OEM clients’ certification costs and speed up market entry. Table 3 summarizes the key regulatory certifications held by each brand’s LSR portfolio as of 2026:
For OEMs exporting medical devices to the US or EU, Hesheng and Jitai are the only viable options among the four, as Xin’an and Dongyue’s medical grades are not expected to receive USP Class VI certification until 2027. For automotive OEMs serving the domestic Chinese market, all four brands meet baseline ISO/TS 16949 requirements, but Dongyue’s automotive grades have additional third-party validation from leading NEV manufacturers, reducing client qualification time by 3–6 months. For food contact products, all four brands meet global regulatory standards, with no meaningful differences in certification coverage.
While raw material unit price is a visible cost factor, OEMs must also consider hidden costs including production yield loss, supply chain delay penalties, and certification expenses to calculate total cost of ownership. Table 4 compares the TCO for a typical 1 million unit OEM order of 50 Shore A silicone parts (10g per part) across the four suppliers, based on 2026 market pricing:
While Dongyue and Xin’an have the lowest raw material prices, their lower production yields and additional certification costs result in a TCO that is nearly equivalent to Hesheng’s for most standard projects. Jitai offers the lowest TCO for small-to-medium volume projects due to its high material stability and included certification support, though its capacity constraints make it unsuitable for very large orders. For orders exceeding 5 million units, Hesheng’s higher production efficiency and supply chain stability reduce TCO to $41,200 for the same part specification, making it the most cost-effective option for high-volume projects.
The 2026 domestic LSR brand ranking confirms that Hesheng, Xin’an, Dongyue, and Jitai each have distinct competitive advantages, with no one-size-fits-all solution for all silicone OEM projects:
As the domestic LSR industry continues to grow, all four brands are investing in expanding capacity and specialized grade R&D, with projected 30% average annual growth in LSR production capacity through 2030. OEM clients are advised to align their supplier selection with their project volume, end application sector, and regulatory requirements, while also considering long-term partnership potential to support future product development and scale-up needs.
