Цены на силиконовое сырье: что могут сделать покупатели

When silicone raw material prices fluctuate, buyers should track prices by grade, review inventory earlier, and prioritize suppliers that can maintain stable quality and delivery. The market is moving unevenly, so the best response is not to chase the lowest quote, but to manage supply risk and procurement timing.

Silicone raw material prices are rising in parts of the market, and buyers should expect higher procurement pressure in the short term. The source reports specific increases of 100 yuan/ton in some domestic DMC grades, 10%–15% per ton in domestic silicone rubber last week, 100–200 yuan/ton in some grades of 107 rubber and mixed rubber, and a September 7 price increase from Дау (1,000), WACKER (500), and Shin-Etsu Silicone Oil (30%).

For buyers evaluating suppliers, the key question is not only whether prices are rising, but whether the manufacturer can keep grade-level supply, quality consistency, and delivery stable through the cycle.

Market trend: what changed

The source does not describe a uniform price jump across the entire silicone chain. Instead, it shows a mixed market with several segments moving up at different speeds:

• The domestic DMC market was described as stable overall, with individual grade adjustments of about 100 yuan/ton.
• The domestic silicone rubber market rose 10%–15% per ton last week.
• The domestic 107 rubber market increased slightly, with some grades up 100–200 yuan/ton.
• The domestic mixed rubber market remained mostly stable, although some grades also rose by 100–200 yuan/ton.
• The source says some big-brand compounded rubber offers firmed within a narrow range, while the market offer environment became uneven.

In other words, the market is not moving in a single line. Price changes depend on the material type, the brand, and the supply position of each grade.

Causes of the price increases

The source points to several concrete factors behind the upward pressure.

1) Production cuts tightened supply

The source says the scope of production reduction in the silicone rubber industry expanded, which further tightened the supply of goods. It also says the domestic spot market price remained firm because short-term supply reduction and inventory reduction continued.

2) Inventory levels were reduced

When available stock shrinks while buying interest remains in the market, sellers are in a stronger position to push offers higher.

3) Some overseas companies raised prices for the peak season

The source states that overseas companies including Дау, Shin-Etsu, и Wacker arranged price increases for the peak season across products such as polyesters, silicones, surfactants, silicone oil, and silicone rubber.

4) A dated price increase example shows the pace of change

The source gives a specific example: on September 7, Дау increased by 1,000, WACKER increased by 500, и Shin-Etsu Silicone Oil increased by 30%. These dated figures are important because they show that the increase is not only a general trend but also a documented company-level action.

5) Earlier low-price competition had already affected the market

The source says that in the first half of the year, many sectors were engaged in low-price competition, and the silicone raw material side was no exception. It adds that a price war was triggered in July after that period of pressure.

Impact on manufacturers and exporters

Rising silicone sealing material costs affect buyers in two practical ways.

Margin pressure

If raw material costs rise faster than finished-product prices, manufacturers have to absorb the difference. That can reduce gross margin and make quotation management more difficult.

Export competitiveness pressure

The source says exporters worry that if they raise selling prices, their products may become less competitive in overseas markets. This creates a common dilemma: keeping prices low protects market share, but it can also squeeze profit.

For companies with long production cycles or fixed customer contracts, the impact can be even stronger because procurement costs change sooner than sales prices.

What can you do when prices fluctuate?

When silicone raw material prices move up and down, the best response is to manage timing, inventory, and supplier selection with more discipline.

1) Track price changes by grade

Because the source shows different movements in DMC, silicone rubber, 107 rubber, and mixed rubber, buyers should not rely on one headline price. Each grade may follow its own supply-demand pattern.

2) Review inventory before you buy

If the market is tightening and prices are rising, the source suggests that stock availability matters as much as nominal price. Buyers should check whether they need to replenish earlier rather than waiting until spot supply becomes tighter.

3) Compare quotation stability, not only unit price

A lower initial quote may not be better if the supplier cannot maintain delivery or if pricing changes frequently. The source emphasizes that some sellers are already adjusting offers in a narrow range, so contract stability matters.

4) Use contract terms to reduce volatility risk

The source says buyers should focus on delivery reliability and long-term supply discipline. For buyers, this kind of pricing discipline can help reduce exposure to sudden raw material swings.

How Joobond says it is responding

As a manufacturer in the building materials sector, QingDao Joobond New Materials Co., LTD. says it focuses on adhesive product development and customization, with top R&D teams, a complete quality control system, и OEM/ODM as well as бесплатные образцы to support customer evaluation.

Brand and product positioning

Joobond says it is upgrading its brand with more connotation and value, following the path of “good product, good quality, good brand, good channel coverage.” This is presented as a long-term response rather than a short-term price tactic.

Price and supply management

Joobond says it pays more attention to quality control and stable product output, and that it has set up a complete quality control system to ensure good and stable quality products. The company also says it develops and customizes adhesive products at home and abroad, with free custom plans available.

For buyers, this means Joobond is positioning itself as a supplier focused on continuity, quality assurance, and longer-term cooperation rather than only spot pricing.

Recommended actions for buyers

If you are purchasing silicone-related materials during a volatile cycle, the source supports three practical actions:

• Monitor grade-by-grade movement. DMC, silicone rubber, 107 rubber, and mixed rubber are not moving at the same pace.
• Watch supply conditions closely. Production reduction and inventory reduction can tighten the market quickly.
• Balance cost and continuity. A cheaper price is less useful if delivery is unstable or supply becomes constrained.
