1、How to Make Plaster with Terpene Resin

As scientific technology advances, terpene resin plasters are expected to see broader development and application. In the future, we hope this innovation will better serve human health, offering patients more effective treatments.

2、The Role of Terpene Resins in Plasters

The functionality of terpene resins in plasters extends beyond physical performance to their bioactive constituents. Many terpene resins contain biologically active compounds, such as flavonoids and volatile oils, which promote blood circulation, relieve muscle tension, and alleviate pain.

多萜（terpene resin）又称萜烯树脂或多萜树脂，是由松节油、β-蒎烯、萜二烯等萜烯类聚合制得的黏稠液至脆性固体的热塑性树脂，其是一种植物天然香料，属烃类树脂，常用作涂料助剂等化工产品。

The Chemistry of Tackifying Terpene Resins

The size dif ference and rigidity of these two types of terpene resins appear to be the outstanding properties which result in the predominant use of beta-pinene resins for pressure sensitive use and dipentene resins for hot melt use.

TERPENE RESINS IN PRESSURE SENSITIVE ADHESIVES

The tackifier resins evaluated in this study were polyterpene, styrenated terpene, and terpene-phenol resins. The softening point for all tackifiers was between 95 and 105oC, except for the limonene resin at 115oC.

Terpene Resins

Making use of terpene, a renewable material, we offer tackifying resins that are indispensable for manufacturing a variety of adhesives. Our tackifying resins provide excellent adhesion performances when formulated with various elastomers including natural rubber and styrene block copolymers.

Terpene resin

As essentially pinene polymers, principally polymers from β-Pinene, the terpene resins exhibit properties typical of polymeric hydrocarbons including chemical inertness.

Polyterpene Resins

Our Polyterpene Resins offer a complete range of softening points, from low to high.

Polyterpene Resisns: Part I – A Brief Historical Review

Commercial adhesive resins are prepared from monoterpenes -the main ones are α-pinene, β-pinene and dipentene. The softening point and molecular weight of polyterpene resins are critical for...

In traditional medicine and household care, plasters are a common topical medication that exert therapeutic effects through skin absorption. when terpene resin plasters begin to harden, it often indicates issues with storage or usage. This article explores the causes of hardening in terpene resin plasters and provides corresponding solutions.

I. Factors Contributing to Hardening of Terpene Resin Plasters

1. Environmental Factors: Temperature and humidity are critical environmental factors affecting plaster hardening. If stored in high-temperature or humid conditions, the chemical components within the plaster may undergo changes, leading to hardening. For example, in summer heat, certain terpene resins may accelerate decomposition, causing the plaster to lose its original softness.

2. Improper Storage Conditions: Incorrect storage methods also contribute to hardening. Storing plasters in direct sunlight or near heat sources (e.g., heaters) accelerates hardening. Additionally, exposing plasters to air without sealing allows moisture and oxygen to react with active ingredients, resulting in hardening.

3. Expiration and Degradation: Over time, the effective components in terpene resin plasters may gradually degrade, reducing efficacy. Expired plasters are more prone to hardening.

II. How to Prevent Hardening of Terpene Resin Plasters

1. Optimal Storage Environment: Store plasters in cool, dry conditions away from sunlight and heat. Use specialized medication storage boxes or airtight bags to protect them from environmental impacts.

2. Proper Storage Practices: For opened plasters, keep them in shaded areas, avoid direct sunlight, and store them away from heat sources (e.g., in a refrigerator).

3. Regular Inspections: Periodically check stored plasters for signs of moisture or spoilage. Discontinue use if abnormal odor, discoloration, or other degradation signs are observed.

4. Safe Disposal of Expired Plasters: Dispose of expired plasters according to local regulations. Avoid casual discarding to prevent environmental and health risks.

III. Solutions for Hardened Terpene Resin Plasters

1. Replace with New Plasters: The most direct solution is to replace hardened plasters with new ones, ensuring therapeutic effectiveness and avoiding health risks associated with expired products.

2. Heat Softening: For specific terpene resin plasters (e.g., herbal-infused types), soaking in warm water followed by gentle massage may soften them. this method applies only to certain formulations and requires medical guidance.

3. Use of Softening Agents: Commercially available plaster-softening products (e.g., adhesive dissolvers) can restore softness. Always follow product instructions and safety guidelines before use.

Hardening of terpene resin plasters is a common issue but does not necessarily render them unusable. By implementing preventive measures and responsive strategies, this problem can be effectively addressed. Prioritizing proper storage, regular inspections, and timely replacement of expired plasters are crucial steps to ensure therapeutic outcomes and patient safety.
