Formulations of alkyd resins with different oil length.
Resin (R1-R3) yang digunakan terdiri dari resin coumarone, resorsinol, dan resin turunan hidrokarbon pada dosis 5 phr. Sementara jenis plasticizer RPO (P1-P3) yang dipelajari dalam riset meliputi
PENGARUH JENIS DAN KONSENTRASI PLASTICIZER TERHADAP SIFAT
Penelitian ini bertujuan untuk mempelajari pengaruh penambahan konsentrasi dan jenis plasticizer yang berbeda terhadap sifat fisik dan kimia edible film yang dihasilkan sehingga dapat diketahui konsentrasi dan jenis plasticizer yang paling tepat untuk menghasilkan edible film terbaik dengan bahan baku kolang kaling. BAHAN DAN METODE
PENGARUH KOMBINASI PLASTICIZER TERHADAP KARAKTERISTIK EDIBLE
Plasticizer yang paling banyak digunakan adalah gliserol dan sorbitol. Beberapa plasticizer lain seperti sukrosa, fruktosa, glukosa dan manosa merupakan pemanis karbohidrat yang memberikan rasa lebih enak pada makanan (Zhang & Han, 2006). Menurut Kokoszka & Lenart (2007), kemampuan plasticizer untuk mengurangi
Pengaruh Jenis Plasticizer Terhadap Karakteristik Plastik
plasticizer berpengaruh pada kuat tarik dan efisiensi plasticizer. Semakin tinggi berat molekul maka kuat tarik edible film akan meningkat [10]. Gambar 3. Grafik Hasil Uji Elongasi dengan Variasi Jenis Plasticizer Jenis plasticizer gliserol dan sorbitol memiliki nilai elongasi yang sama (3,33%) sedangkan
PENGARUH PLASTICIZER PADA KARAKTERISTIK EDIBLE FILM DARI PEKTIN
untuk mengetahui pengaruh kadar dan jenis plasticizer terhadap kuat tarik, persentase elongation dan permeabilitas uap air dari pektin edible film. Plasticizer yang digunakan dalam penelitian ini adalah sorbitol dan gliserol. Serbuk albedo dari kulit jeruk bali dihidrolisis dengan larutan asam klorida 0,1 N untuk mendapatkan pektin.
- How to determine plasticizer compatibility?
- The solubility parameter methods are useful tools for estimating plasticizer compatibility. There exists an optimum range of molecular weights for plasticizer efficiency. Lower Mw plasticizers have a noticeable plasticization effect than their higher counterparts.
- What is plasticizer selection?
- Plasticizer selection involves trying to meet a combination of end-use performance requirements, processing needs, cost, and in some cases, specific regulatory requirements. Products produced from flexible PVC are used in a wide range of applications and industry market segments.
- How to make a plastic product more flexible by adding plasticizers?
- The process of making the final plastic product more flexible by adding plasticizers is called plasticization. By adding the right type and amount of plasticizer, you can tweak the polymer properties to get exactly what you need.
- How do plasticizers affect a polymer?
- Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers.
- Why are plasticizers important?
- Plasticizers prevent the development of microcracks in the polymer matrix. They thereby enhance material durability and resistance to mechanical stress. Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
