Warframe is a huge and immersive game that players can sink hundreds of hours into. There are many Warframes, weapons, Archwings, companions, and more to obtain and build as well as dozens of resources. Polymer Bundle is a resource that players will need a lot of as they look to build different things and progress through their Mastery ranks.
Polymer Bundle is an uncommon component that can be found on just a few planets - Mercury, Venus, and Uranus. As such all of the nodes for obtaining Polymer Bundle can be found there. Polymer usually spawns in quantities of 40-80 making it quite a slow grind considering the amount a player will need to build everything. Warframe is one of the best free shooting games on PC, and it's a great source of fun and reward for players.
6 Apollodorus - Mercury
Apollodorus is the place for players to go when they are extremely early-level into the game. It is unlikely that any player will stay for too long on Mercury. Survival missions such as Apollodorus are recommended for Polymer Bundle, due to the mission objective giving the player a reason to travel around the map searching for Life Support Modules anyway.
Enemies are only between levels 6-11 on this mission, so pretty much anything can take them down pretty quickly. Players don't have to worry about struggling on this planet, and should focus on trying out beginner Warframe mods as well as different weapons in order to learn more about the game.
5 Romula - Venus
Romula is a Dark Sector Defense mission with level 8-18 enemies on the Corpus Ship tile set. Players running early-game Warframes such as Frost may enjoy playing here, as he is one of the best Defense Warframes and can get a ton of Affinity for playing the objective.
Polymer Bundle has a reasonable drop rate on Romula due in part to the Dark Sector drop rate bonus. Being a Defense mission, lots of enemies congregate in one spot to attack the objective, meaning players can get extra Polymer Bundle as drops from enemies as well as taking the time to traverse the map-breaking containers. Running a Nekross with Desecrate is a great way of securing more loot from each run.
4 Malva - Venus
A Dark Sector Survival mission with enemies ranging from level 8-18, Malva follows the Corpus Ship tileset. The enemies are not very difficult, allowing players to bring unranked or low-ranked weapons and Warframes in order to earn some Affinity while farming for Polymer Bundle. Venus is a great way to farm Rhino, a Warframe everyone should know, so players shouldn't be surprised to spend a little time on Venus.
Malva is a Dark Sector mission meaning it has a higher drop chance, so Tenno will collect a reasonable amount of Polymer Bundle considering how early into the game they are. When the player unlocks more in the Star Chart, they should definitely look to move on from Malva as pales in comparison to the drop rates on other missions.
3 Ophelia - Uranus
Ophelia is a level 24-29 Survival mission on Uranus' Grineer Sealab tile set. The enemies are a little tough at this point, but nothing that decent weapons and a Rank 10 + Warframe can't handle. Players should avoid the classic Warframe beginner mistake of taking Rank 0 equipment on a difficult planet such as Uranus.
The Survival mission type means players will encounter Polymer Bundle from all the containers, crates, and caches around the map as well as from the corpses of dead Grineer. Running Loot Detector and a Desecrate Nekross aids the farming process further.
2 Any Void Relic Mercury Mission
There are tons of Void Relics that all give the player a selection of various Prime parts upon completing a Void Relic mission. Since there are tons of Prime weapons, Warframes, Archwings, etc, a lot of time is spent by players farming Void Relics since Prime versions are always better than the non-Prime variant. Some of the best Warframe shotguns in the game are Prime variants, for example.
Void Relic missions rotate constantly, but at times there will be missions on Mercury. Players that are looking to farm Void Relics, as well as Polymer Bundle, should take advantage of the efficiency of farming for multiple things at the same time. This saves the Tenno time in the long run and leads to a more efficient way of playing the game.
1 Assur - Uranus
A Dark Sector Survival mission on Uranus, Assur is the best place in Warframe for farming Polymer Bundle. It has level 25-35 enemies and runs the Grineer Galleon tile set. Being a Dark Sector mission, Polymer Bundle has an increased drop rate.
Assur is also a great place for farming Plastids and Gallium, making it a very useful node for players in general. Players should be taking Warframes and weapons of at least a decent rank (10 +), but the enemies are not so difficult especially when running the mission in public lobbies.
Warframe is available on PC, PlayStation 4, Xbox One, PlayStation 5, Xbox One Series X|S, and Nintendo Switch.
