Polymer stabilizers
Polymer stabilizers (British: polymer stabilisers) are chemical additives which may be added to polymeric materials, such as plastics and rubbers, to inhibit or retard their degradation. [1] Common polymer degradation processes include oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well
Mesamoll | The universal plasticizer | LANXESS
Mesamoll is a non-phthalate, well-gelling and exceptionally saponification-resistant universal plasticizer for a wide range of polymers, such as PVC, PUR and rubber. Plasticizers By incorporation of plasticizers into compatible polymers, the materials can be modified in such a way that it becomes soft and flexible, even at sub-zero temperatures.
Plasticizers: Types, Uses, Classification, Selection & Regulation
The most widely used internal plasticizer monomers are: Vinyl acetate Vinylidene chloride But this technique is limited: every copolymer is only suited to certain flexibility requirements Also, the complexity of the reaction can lead to longer reaction times and increased costs.
Application of Different Vegetable Oils as Processing Aids
(1) The use of processing oils or plasticizers is by far the most effective way to enhance the interaction between the rubber and filler by increasing the compatibility. (2) Petroleum oils with polycyclic aromatic hydrocarbons (PAHs) are generated via the petroleum refining process.
Lubrication and plasticization behavior of large-size micro-spherical
It may be attributed to its effective lubricating and plasticizing effect on rubber which rubber chains can adjust conformation in time to obstruct the micro-crack damage and spread.40 It also probably because the compound has experienced greater thermal history during mixing due to this more efficient slide between molecules to consume a large
- Which plasticizer is best for nitrile rubber?
- Special application information to note on our plasticizer brands in nitrile rubber : Plasthall ® 7050 – Fuel B resistance, LT, HT, oil resistance, limited use with low ACN. Poor water resistance. Plasthall ® 83SS – Fuel C resistance, LT, HT. Plasthall ® 4141 – Good unaged and heat aged LT, #3 oil resistance, FDA Regulation 177.2600.
- Can Plasticizers improve rubber properties?
- Technological advancements, such as 3D printing and additive manufacturing, also play a pivotal role. These technologies herald new possibilities in rubber formulation, where plasticizers can be fine-tuned to enhance material properties significantly.
- Can bio-based Plasticizers improve the biodegradability of rubber products?
- Bio-based plasticizers such as epoxidized vegetable oils, which are sourced from natural oils, have gained traction. They deliver similar, if not superior, performance characteristics without the environmental baggage. Moreover, several studies have shown that these alternatives can enhance the biodegradability of rubber products.
- Why is temperature important when mixing plasticizers with rubber?
- Processing temperature is a critical factor when mixing plasticizers with rubber. An effective plasticizer reduces the viscosity of rubber, making it easier to mold and process. This aspect is particularly important in industrial settings where efficiency directly correlates with productivity.
- What is the role of plasticizers in rubber formulation?
- The role of plasticizers in rubber formulation is often overlooked, yet it stands as a cornerstone of material science that significantly enhances the usability and adaptability of rubber products.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
