E-books about elastomers exist due to the growing interest in the science and technology of engineered elastomers. Elastomer Ebook | Page 4 Preface START WITH Some of these books provide a broad survey of elastomers with special emphasis on materials with a rubber-like elasticity, while others focus on specific types of elastomers, such as natural and synthetic rubbers, rubber-blends, rubber composites, and thermoplastic elastomers. Additionally, there is a book that provides facts, vivid pictures of slime, methods, background study, results and discuss about slime. These books cover a wide range of topics related to elastomers and rubbery materials, including theoretical and practical information on characterizing rubbers, designing engineering elastomers for consumer and engineering applications, properties testing, chemical and physical property characterization, polymerization chemistry, rubber processing and fabrication methods, and rheological characterization.
INTRODUCTION Do you know what is elastomers? Why slime is consider as one of the elastomers? Elastomers are Elastic Polymers, also known as any rubbery material composed of long chainlike molecules or polymers. Elastomers have elastic properties which causes it to easily recovering to their original shape after being stretched to great extents. Slime made up from Poly(vinyl acetate) or PVA and capable of returning back to its original shape even after being stretch, twisted or compressed. Hence, Slime is an Elastomer SLIME AN ELASTOMER Objectives of the projects is to : 1) To modify polymer to enhance its properties. 2) To characterize the polymer properties using physical or visual characterization.

Slime is known to have unique properties such as can bounce, elastic, can be stretch and not goopy which make it easier for us to hold it (Ibis, 2020). However, according to Barnes, 2023, slimes can break apart even though they have elastic properties when we quickly stretch or pull the slimes. They also can break aparts when contain of too much activator in the mix. Too much amount of activator also causes the slime to become hard and rubbery. This condition is called as overactivated slime. Plus, slimes become sticky due to low number of strings of polymer. Elastomer Ebook | Page 6 STUDY BACKGROUND OF Thus, this project is carried out to enhance its properties by modifying the polymer using clear glue, hot water and salt so that the slimes become more elastic, less sticky and hard to break apart.
How to make a Slime? Elastomer Ebook | Page 7 Methods OF MODIFICATION AND CHARACTERIZATION 01 Add 100ml of clear PVA glue into the bowl. ADDITION OF CLEAR FLUE 02 Add 100ml of hot water gradually into the same bowl. ADDITION OF HOT WATER Materials: 100ml Clear PVA Glue 100ml Hot Water 1 Tablespoon of Salt Apparatus: Spoon 3 Bowl 05 The consistency of the mixture can be adjusted to our liking with the addition of hot water 5ml, 10ml and 15 ml. ADJUST CONSISTENCY 03 Add 1 tablespoon of salt into the mixture in the same bowl. ADDITION OF SALT PROCEDURES 04 Stir the mixture until the salt completely dissolve and slime appear. STRIRRING

1) STRESS RELIEVER TOY For adults, slime can be used as a stress reliever since the soft and sticky texture of slime helps us to become more relaxed. Playing with slime reduces the stress and we will become more calm. 4) SENSORY kit Slime as the sensory toy for kids allow kids to improve their motor skills in an innovative way. As playing with slime requires the movement of their hands and eyes, this will helps to improve kids' practical strength and fine motor control. Elastomer Ebook | Page 9 2) EDUCATIONAL TOOL Especially in learning science, slime can be used to teach students the science principles such as chemical reactions, viscosity and polymers. Depending on how slime is used based on nonNewtonian fluid, polymer substance made up of slime can act as liquid or solid. 3) CLEANING SLIME Function like a lint brush that brush off dust or small particles on small spaces like on keyboard and other electronic devices. Cleaning slimes are usually thicker. POTENTIAL APPLICATIONs
The adjustment in the amount of few materials has improve the texture of the slime for it to have better cleaning properties. The modification will only be simple because just three materials are required to make this slime. Here are the things we noticed throughout the experiment: Elastomer Ebook | Page 10 RESULTS AND DISCUSSION The addition of clear glue will make the slime harder and easy to break. The addition of hot water will make the slime softer and more elastic. The addition of salt in the mixture will add more cross-linking within the bonds in the slime. Due to these considerations, the mixed material must be made gradually and in phases in order to achieve the required consistency or texture. Colour and tiny beads can be added to make it more appealing.
RESULTS AND DISCUSSION Time taken for the slime to fill the empty space Elastomer Ebook | Page 11 From what we can see from the video, slime with the most addition of water (15ml) is the most elastic mixture and it takes the shortest amount of time to fill in the empty space in the bowl. Slime with the least addition of water (5ml) is the most hard one. Slime making video please click the relevant box to go to the video link Slime with the addition of 5ml water is the most hard one and has the longest amount of time taken to fill in the empty space in the bowl. The slime with addition of 10ml water falls in between
CONCLUSION In daily life, slime can be used as a sensory tool, for cleaning, and for educational purposes. With a few basic ingredient, we can make slime at home. By increasing or decreasing the amount of the ingredients in the mixture, slime's consistency can be changed to suit its intended usage. Elastomer Ebook | Page 12
